Overview

Configuring Row-Level Security (RLS) group membership is a key governance and scalability topic within the “Manage and secure Power BI (15–20%)” domain of the PL-300: Microsoft Power BI Data Analyst certification exam. This topic builds on basic RLS concepts and focuses on how users are assigned to RLS roles, with an emphasis on using Microsoft Entra ID (Azure AD) security groups instead of individual users.

For the exam, you should understand where RLS roles are defined, where group membership is configured, how group-based RLS behaves, and why it is considered a best practice.


What Is RLS Group Membership?

RLS group membership refers to assigning security groups (rather than individual users) to Row-Level Security roles in a Power BI semantic model. Any user who is a member of the group automatically inherits the data access defined by the role.

This approach:

  • Improves scalability
  • Simplifies administration
  • Aligns with enterprise security standards
  • Reduces ongoing maintenance

Exam Focus: The PL-300 exam strongly favors group-based RLS as the recommended approach.


Where RLS Group Membership Is Configured

Understanding where actions occur is frequently tested.

Power BI Desktop

  • Create RLS roles
  • Define DAX filter expressions
  • No users or groups are assigned here

Power BI Service

  • Assign users or security groups to RLS roles
  • Manage role membership after publishing

Key Distinction:

  • Roles and filters → Desktop
  • Users and groups → Service

Why Use Security Groups for RLS?

Benefits of Group-Based RLS

  • Centralized identity management
    Groups are managed in Microsoft Entra ID, not Power BI.
  • Automatic access updates
    Adding or removing users from a group instantly updates data access.
  • Reduced administrative effort
    No need to modify RLS settings when staff changes.
  • Auditability and compliance
    Easier to review who has access and why.

Exam Tip: If a question asks for the most scalable or best practice approach, choose security groups.


Types of Groups Used in RLS

Supported Group Types

  • Microsoft Entra ID security groups (recommended)
  • Mail-enabled security groups

Not Recommended / Not Supported

  • Distribution lists (not ideal for security)
  • Microsoft 365 groups (not designed for RLS scenarios)

PL-300 Expectation: Know that security groups are the preferred option for RLS role membership.


Assigning Groups to RLS Roles

Step-by-Step (Power BI Service)

  1. Publish the semantic model from Power BI Desktop
  2. In the Power BI Service, open the semantic model
  3. Select Security
  4. Choose an RLS role
  5. Add one or more security groups
  6. Save changes

Once assigned, all group members inherit the role’s data filters.


Group Membership and Dynamic RLS

Group membership is often combined with dynamic RLS for maximum flexibility.

Common Pattern

  • RLS role contains a dynamic filter using USERPRINCIPALNAME()
  • A mapping table links users to business entities (e.g., region, department)
  • A security group controls who is subject to that role

This pattern:

  • Minimizes the number of roles
  • Supports large organizations
  • Separates identity management from data logic

How Group-Based RLS Is Evaluated

When a user opens a report:

  1. Power BI identifies the user’s Entra ID group memberships
  2. The user is matched to assigned RLS roles
  3. The union of all applicable role filters is applied
  4. Only authorized rows are returned

Important Exam Concept:
Users in multiple roles see the combined (union) of allowed data—not the most restrictive set.


Testing Group-Based RLS

In Power BI Desktop

  • Use View as
  • Test role logic only (group membership is not evaluated here)

In Power BI Service

  • Use View as role
  • Or test by signing in as a user who belongs to the group

Exam Awareness: Group membership itself cannot be fully tested in Desktop—only in the Service.


Common Pitfalls (Exam-Relevant)

  • Assigning individual users instead of groups
  • Expecting RLS to apply before publishing
  • Forgetting that group membership changes happen outside Power BI
  • Confusing workspace roles with RLS roles
  • Assuming admins bypass RLS automatically

RLS Group Membership vs Workspace Roles

FeatureWorkspace RolesRLS Group Membership
Controls content access
Controls data visibility
Uses Entra ID groups
Defined in Desktop
Assigned in Service

PL-300 Focus: These are complementary—not interchangeable—security mechanisms.


Governance and Best Practices

  • Always prefer security groups over individuals
  • Use clear, business-aligned group names
  • Keep RLS logic simple and documented
  • Coordinate with identity administrators
  • Review group membership regularly

Common Exam Scenarios

You may be asked to identify:

  • The best way to manage RLS for hundreds of users
  • Why a user gained or lost data access without a model change
  • Where to update access when an employee changes roles
  • How group membership impacts RLS evaluation

Key Takeaways for the PL-300 Exam

  • RLS roles are defined in Power BI Desktop
  • Group membership is configured in the Power BI Service
  • Microsoft Entra ID security groups are the recommended approach
  • Group-based RLS improves scalability and governance
  • Users see the union of all assigned RLS roles
  • RLS applies to all reports and apps using the semantic model

Implement Row-Level Security (RLS) Roles (PL-300 Exam Prep)

This post is a part of the PL-300: Microsoft Power BI Data Analyst Exam Prep Hub; and this topic falls under these sections:
Manage and secure Power BI (15–20%)
--> Secure and govern Power BI items
--> Implement Row-Level Security (RLS) Roles


Note that there are 10 practice questions (with answers and explanations) at the end of each topic. Also, there are 2 practice tests with 60 questions each available on the hub below all the exam topics.

Overview

Implementing Row-Level Security (RLS) is a critical skill for Power BI Data Analysts and a key topic within the “Manage and secure Power BI (15–20%)” domain of the PL-300: Microsoft Power BI Data Analyst certification exam. RLS ensures that users only see the data they are authorized to view, even when accessing the same reports or semantic models.

For the exam, you must understand how RLS roles are created, how they are implemented using DAX, how users and groups are assigned, and how RLS behaves in the Power BI Service.


What Is Row-Level Security?

Row-Level Security restricts access to specific rows of data in a semantic model based on the identity of the user viewing the report.

RLS:

  • Is defined in Power BI Desktop
  • Uses DAX filter expressions
  • Is enforced in the Power BI Service
  • Applies to all reports that use the semantic model

Key Concept: RLS controls data visibility, not report visibility.


RLS Architecture in Power BI

The RLS workflow consists of four main steps:

  1. Define roles in Power BI Desktop
  2. Create DAX filter expressions for tables
  3. Publish the semantic model to the Power BI Service
  4. Assign users or groups to roles in the Service

Each role defines which rows are visible when the user is a member of that role.


Creating RLS Roles in Power BI Desktop

Step 1: Create Roles

In Power BI Desktop:

  • Go to Model view or Report view
  • Select Modeling → Manage roles
  • Create one or more roles (e.g., SalesWest, SalesEast)

Roles are placeholders until users or groups are assigned in the Power BI Service.


Step 2: Define Table Filters (DAX)

RLS is implemented using DAX filter expressions applied to tables.

Example: Static RLS

[Region] = "West"

This filter ensures that users assigned to the role only see rows where Region equals West.

Exam Tip: RLS filters act like WHERE clauses and reduce visible rows—not columns.


Static vs Dynamic RLS

Static RLS

  • Filters are hardcoded values
  • Each role represents a specific segment
  • Easy to understand, but not scalable

Example:

[Department] = "Finance"


Dynamic RLS (Highly Exam-Relevant)

Dynamic RLS uses the logged-in user’s identity to filter data automatically.

Common functions:

  • USERPRINCIPALNAME()
  • USERNAME()

Example:

[Email] = USERPRINCIPALNAME()

Dynamic RLS:

  • Scales well
  • Reduces number of roles
  • Is commonly used in enterprise models

Best Practice: Use dynamic RLS with a user-to-dimension mapping table.


Assigning Users to RLS Roles (Power BI Service)

After publishing the semantic model:

  1. Go to the Power BI Service
  2. Navigate to the semantic model
  3. Select Security
  4. Assign users or Microsoft Entra ID (Azure AD) groups to roles

Best Practice: Always assign security groups, not individual users.


Testing RLS

In Power BI Desktop

  • Use Modeling → View as
  • Test roles before publishing
  • Validate DAX logic

In Power BI Service

  • Use View as role
  • Confirm correct filtering for assigned users

Exam Tip: “View as” does not bypass RLS—it simulates user access.


RLS Behavior in Common Scenarios

Reports and Dashboards

  • RLS applies automatically
  • Users cannot see restricted data
  • Visual totals reflect filtered data

Power BI Apps

  • RLS is enforced
  • No additional configuration required

Analyze in Excel / External Tools

  • RLS is enforced if the user has Build permission
  • Users cannot bypass RLS through external connections

Important RLS Limitations (Exam Awareness)

  • RLS does not hide tables or columns (use Object-Level Security for that)
  • RLS cannot be applied directly to measures
  • Workspace Admins are not exempt from RLS unless explicitly configured
  • RLS does not apply in Power BI Desktop for the model author unless using “View as”

Object-Level Security (OLS) vs RLS

FeatureRLSOLS
Controls rows
Controls columns/tables
Configured in Desktop❌ (External tools)
Exam depthHighAwareness only

PL-300 Focus: RLS concepts are tested far more deeply than OLS.


Governance and Best Practices

  • Use dynamic RLS wherever possible
  • Centralize security logic in the semantic model
  • Use groups, not individuals
  • Document role logic for maintainability
  • Test RLS thoroughly before sharing reports

Common Exam Scenarios

You may be asked to determine:

  • Why different users see different values in the same report
  • How to reduce the number of RLS roles
  • How to implement user-based filtering
  • Where RLS logic is created vs enforced

Key Takeaways for the PL-300 Exam

  • RLS restricts row-level data visibility
  • Roles and filters are created in Power BI Desktop
  • Users and groups are assigned in the Power BI Service
  • Dynamic RLS uses USERPRINCIPALNAME()
  • RLS applies to all reports and apps using the semantic model
  • RLS is enforced at the semantic model level

Configure Access to Semantic Models (PL-300 Exam Prep)

This post is a part of the PL-300: Microsoft Power BI Data Analyst Exam Prep Hub; and this topic falls under these sections:
Manage and secure Power BI (15–20%)
--> Secure and govern Power BI items
--> Configure Access to Semantic Models


Note that there are 10 practice questions (with answers and explanations) at the end of each topic. Also, there are 2 practice tests with 60 questions each available on the hub below all the exam topics.

Overview

Configuring access to semantic models (formerly known as datasets) is a core responsibility of a Power BI Data Analyst and a key topic within the “Manage and secure Power BI (15–20%)” domain of the PL-300 exam. This topic focuses on how access to data models is controlled, shared, governed, and secured so that users can interact with data appropriately—without compromising data integrity or confidentiality.

For the exam, you should understand how semantic models are shared, who can access them, what level of access they have, and how security is enforced at both the model and row level.


What Is a Semantic Model in Power BI?

A semantic model is the business-ready representation of data in Power BI. It includes:

  • Tables, relationships, and hierarchies
  • Measures, calculated columns, and KPIs
  • Data formatting and metadata
  • Security rules (such as Row-Level Security)

Semantic models are published to the Power BI Service and act as the foundation for reports, dashboards, and analysis.


Access Control Concepts You Must Know

Workspace Roles

Access to semantic models is primarily governed by workspace roles in the Power BI Service:

RoleCapabilities Related to Semantic Models
ViewerCan view reports and read data (if permitted)
ContributorCan create and edit content, including reports
MemberCan publish, update, and share semantic models
AdminFull control, including managing permissions and security

Exam Tip: Viewers cannot create new reports from a semantic model unless Build permission is explicitly granted.


Semantic Model Permissions

Semantic models support item-level permissions, separate from workspace roles.

Key permissions include:

  • Read – Allows users to view data used in reports
  • Build – Allows users to create new reports using the semantic model
  • Reshare – Allows users to share the semantic model with others

These permissions can be assigned to:

  • Individual users
  • Security groups
  • Microsoft Entra ID (Azure AD) groups

Best Practice: Grant access using security groups instead of individual users for scalability and easier management.


Build Permission (Highly Exam-Relevant)

Build permission is one of the most tested concepts in this topic.

With Build permission, users can:

  • Create new reports using the semantic model
  • Use the model in Excel (Analyze in Excel)
  • Use the model via external tools (when allowed)

Without Build permission:

  • Users can view reports
  • Users cannot create new reports from the model

Build permission can be granted:

  • Automatically through workspace role (Member/Admin)
  • Manually on the semantic model
  • Via sharing settings

Sharing Semantic Models

Semantic models can be shared in several ways:

  • Through workspace access
  • By directly sharing the semantic model
  • By publishing reports that use the model
  • Via Power BI Apps

When sharing, you can choose whether recipients:

  • Can build new content
  • Can reshare the model
  • Are restricted by existing security rules

Exam Scenario: A user can view a report but cannot create their own—this often indicates missing Build permission.


Row-Level Security (RLS)

Row-Level Security restricts which rows of data a user can see within a semantic model.

Key RLS concepts:

  • Roles are defined in Power BI Desktop
  • DAX filters control row visibility
  • Users or groups are assigned to roles in the Power BI Service
  • RLS applies to all reports using the model

Types of RLS:

  • Static RLS – Fixed filters (e.g., Region = “West”)
  • Dynamic RLS – Filters based on the logged-in user (e.g., USERPRINCIPALNAME())

Important: RLS is enforced at the semantic model level, not the report level.


Object-Level Security (OLS) (Awareness Level)

While not deeply tested, you should be aware that Object-Level Security can:

  • Hide tables, columns, or measures from specific users
  • Be configured using external tools (e.g., Tabular Editor)

OLS complements RLS but is more advanced and typically managed by model developers.


Certified Dataset / Endorsed Semantic Models

To support governance, Power BI allows semantic models to be endorsed:

  • Promoted – Indicates the model is reliable and ready for reuse
  • Certified – Officially validated and approved by data owners or admins

Endorsements help users:

  • Identify trusted data sources
  • Avoid using unofficial or duplicate models

Exam Tip: Certification requires specific tenant permissions and approval workflows.


Power BI Apps and Semantic Models

When distributing content via a Power BI App:

  • Access to the semantic model is controlled through the app
  • Users can be allowed to connect to the underlying semantic model
  • RLS still applies

Apps provide a controlled, read-only distribution method while maintaining centralized security.


Common Exam Scenarios

You may be asked to determine:

  • Why a user cannot build a report from an existing model
  • How to allow self-service reporting without giving full workspace access
  • How to restrict data visibility for different users
  • Which permission or role best fits a business requirement

Key Takeaways for the PL-300 Exam

  • Semantic models are secured through workspace roles and item-level permissions
  • Build permission is essential for report creation and analysis
  • Row-Level Security controls data visibility per user
  • Use groups, not individuals, for scalable access control
  • Endorsed and certified models support governance and trust
  • Security is applied at the semantic model level, not per report

Just a FYI … this topic emphasizes balancing self-service analytics with strong data governance, a recurring theme throughout the PL-300 exam.

Configure Item-Level Access in Power BI (PL-300 Exam Prep)

This post is a part of the PL-300: Microsoft Power BI Data Analyst Exam Prep Hub; and this topic falls under these sections:
Manage and secure Power BI (15–20%)
--> Secure and govern Power BI items
--> Configure Item-Level Access


Note that there are 10 practice questions (with answers and explanations) at the end of each topic. Also, there are 2 practice tests with 60 questions each available on the hub below all the exam topics.

Overview

Item-level access in Power BI controls who can access specific Power BI items—such as reports, dashboards, semantic models (datasets), and apps—and what actions they can perform on those items.

This topic is part of the Manage and secure Power BI (15–20%) exam domain and falls specifically under Secure and govern Power BI items, making it a critical governance concept for PL-300 candidates.

Unlike workspace roles (which define broad permissions across an entire workspace), item-level access allows more granular control over individual Power BI assets.


What Is Item-Level Access?

Item-level access refers to permissions assigned directly to individual Power BI items, independent of workspace roles. These permissions determine whether users can:

  • View an item
  • Share an item
  • Build new content using an item
  • Reshare or export data
  • Modify or manage the item

Item-level access is commonly configured for:

  • Reports
  • Dashboards
  • Semantic models (datasets)
  • Apps (indirectly through audience access)

Why Item-Level Access Matters (Exam Perspective)

From a PL-300 standpoint, item-level access is important because it helps:

  • Enforce principle of least privilege
  • Enable self-service BI safely
  • Separate content creation from content consumption
  • Support enterprise governance without duplicating workspaces

Expect exam questions that test when to use item-level permissions instead of workspace roles, and how item-level access interacts with security features like RLS.


Configuring Item-Level Access by Item Type

1. Report-Level Access

Reports can be shared directly with users or groups.

Key capabilities:

  • View report
  • Share report (optional)
  • Build new content (if underlying model allows it)

How it’s configured:

  • Use the Share button on a report
  • Assign access to users, security groups, or distribution lists

Important exam note:
Sharing a report does not automatically grant access to the underlying semantic model unless explicitly allowed.


2. Dashboard-Level Access

Dashboards are typically shared for executive or summary-level consumption.

Key characteristics:

  • View-only by default
  • No data modeling or editing
  • Tiles link back to underlying reports (which require separate access)

Exam tip:
Users must also have access to the source reports behind dashboard tiles to avoid broken visuals.


3. Semantic Model (Dataset) Item-Level Access

Semantic models support some of the most important item-level permissions.

Key permissions:

  • Read – view reports using the model
  • Build – create new reports or analyze in Excel
  • Reshare – share the dataset with others

Common use case:

  • Grant Build permission to analysts so they can create their own reports without modifying the dataset.

Exam highlight:
The Build permission is essential for self-service BI scenarios and is frequently tested.


4. App Access (Audience-Based)

Apps use audiences to control item-level visibility.

What audiences allow you to do:

  • Show different content to different user groups
  • Hide specific reports or dashboards
  • Control navigation and access without duplicating content

Best practice:

  • Use Azure AD security groups for app audiences.

Item-Level Access vs Workspace Roles

FeatureWorkspace RolesItem-Level Access
ScopeEntire workspaceIndividual items
GranularityCoarseFine-grained
Best forContent creators/adminsConsumers & self-service
Exam focusGovernanceSecurity precision

Key exam takeaway:
Workspace roles control what users can do, while item-level access controls what items they can access.


Item-Level Access and Row-Level Security (RLS)

These two are often confused on the exam.

  • Item-level access controls access to content
  • RLS controls data visibility within content

They are complementary, not interchangeable.

Example scenario:

  • Item-level access → Can the user open the report?
  • RLS → What rows of data does the user see after opening it?

Best Practices for Configuring Item-Level Access

  • Use Azure AD security groups instead of individuals
  • Grant Build permission carefully
  • Avoid oversharing datasets
  • Combine item-level access with RLS for data security
  • Prefer apps and audiences for large-scale distribution

Common Exam Traps to Watch For

  • Assuming report sharing grants dataset access automatically
  • Confusing workspace roles with item permissions
  • Forgetting that dashboard tiles require report access
  • Overlooking Build permission in self-service scenarios

Summary for PL-300 Exam Readiness

To succeed on PL-300 questions about item-level access, you should be able to:

✔ Identify when item-level access is required
✔ Configure permissions for reports, dashboards, and datasets
✔ Understand Build vs Read permissions
✔ Explain how item-level access differs from workspace roles
✔ Combine item-level access with RLS appropriately

Assign Workspace Roles (PL-300 Exam Prep)

This post is a part of the PL-300: Microsoft Power BI Data Analyst Exam Prep Hub; and this topic falls under these sections:
Manage and secure Power BI (15–20%)
--> Secure and govern Power BI items
--> Assign Workspace Roles


Note that there are 10 practice questions (with answers and explanations) at the end of each topic. Also, there are 2 practice tests with 60 questions each available on the hub below all the exam topics.

Overview

In Power BI, workspaces are collaborative containers used to develop, manage, and distribute content such as semantic models (datasets), reports, dashboards, dataflows, and apps.
Assigning workspace roles is a core governance task that ensures users have the appropriate level of access—no more and no less—based on their responsibilities.

For the PL-300 exam, you are expected to understand:

  • The four workspace roles
  • What each role can and cannot do
  • When to assign each role
  • How workspace roles relate to security, governance, and content lifecycle

Power BI Workspace Roles

Power BI provides four predefined workspace roles:

1. Admin

Highest level of access

Admins have full control over the workspace and its contents.

Key capabilities:

  • Add or remove users and assign roles
  • Update workspace settings
  • Publish, update, and delete all content
  • Configure semantic model settings (refresh, credentials, endorsements)
  • Publish and update workspace apps
  • Delete the workspace

Typical use cases:

  • Power BI service administrators
  • BI platform owners
  • Lead analytics engineers

🔑 Exam tip: Only Admins can manage workspace access and delete a workspace.


2. Member

Content creators and managers

Members can actively create and manage content, but they cannot manage workspace access.

Key capabilities:

  • Create, edit, and delete reports and dashboards
  • Publish semantic models
  • Configure scheduled refresh
  • Publish and update workspace apps
  • Share content (depending on tenant settings)

Limitations:

  • Cannot add or remove workspace users
  • Cannot delete the workspace

Typical use cases:

  • Power BI developers
  • Data analysts responsible for production content

3. Contributor

Content creators without publishing authority

Contributors can build and modify content, but they cannot publish apps or manage access.

Key capabilities:

  • Create and edit reports and semantic models
  • Upload PBIX files
  • Modify existing content they have access to

Limitations:

  • Cannot publish or update workspace apps
  • Cannot manage workspace users
  • Cannot change workspace settings

Typical use cases:

  • Analysts building reports for review
  • Developers working in shared or pre-production workspaces

4. Viewer

Read-only access

Viewers can consume content but cannot modify anything.

Key capabilities:

  • View reports, dashboards, and apps
  • Interact with visuals (filters, slicers)
  • Export data (if allowed)

Limitations:

  • Cannot create or edit content
  • Cannot publish apps
  • Cannot configure refresh or settings

Typical use cases:

  • Business users
  • Executives and stakeholders
  • Consumers of certified content

🔑 Exam tip: Viewers require a Power BI Pro license unless the workspace is in Premium capacity.


Assigning Workspace Roles

Workspace roles are assigned in the Power BI service:

  1. Navigate to the workspace
  2. Select Access
  3. Add users or groups
  4. Assign the appropriate role (Admin, Member, Contributor, Viewer)

🔐 Best practice: Assign Azure AD security groups instead of individual users to simplify governance and reduce maintenance.


Governance and Security Considerations

Least Privilege Principle

Always assign the lowest role necessary for a user to perform their job.

  • Consumers → Viewer
  • Report authors → Contributor or Member
  • Platform owners → Admin

Separation of Duties

Use different workspaces for:

  • Development
  • Testing
  • Production

Assign higher roles in dev, more restrictive roles in prod.

Workspace Roles vs Item-Level Security

  • Workspace roles control what users can do
  • Row-level security (RLS) controls what data users can see

Both are often used together.


Common Exam Scenarios

You may see questions such as:

  • Which role allows a user to publish an app but not manage access?Member
  • Which role is required to assign users to a workspace?Admin
  • Which role should be assigned to report consumers?Viewer
  • Why use Contributor instead of Member? → To prevent app publishing or access management

Key Takeaways for PL-300

  • Know all four workspace roles
  • Understand capabilities vs limitations
  • Admin = access + settings
  • Member = manage content + apps
  • Contributor = build content only
  • Viewer = consume content only
  • Assign roles strategically for security and governance
