This post is a part of the PL-300: Microsoft Power BI Data Analyst Exam Prep Hub; and this topic falls under these sections:
Visualize and analyze the data (25–30%)
--> Enhance reports for usability and storytelling
--> Configure sync slicers
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
Sync slicers in Power BI allow report designers to apply the same slicer selection across multiple report pages, ensuring a consistent filtering experience as users navigate a report. For the PL-300: Microsoft Power BI Data Analyst exam, you are expected to understand when to use sync slicers, how to configure them, and how they impact report usability and storytelling.
Why Sync Slicers Are Important
Without synced slicers, users must repeatedly reapply the same filters on every page, which can lead to:
- Confusion or inconsistent analysis
- Frustration for business users
- Misinterpretation of results across pages
Sync slicers help maintain context continuity, especially in multi-page analytical reports.
What Are Sync Slicers?
A sync slicer ensures that:
- The selection state of a slicer is shared across selected pages
- The slicer can be visible or hidden independently on each page
- Filter context remains consistent as users navigate the report
Sync slicers control slicer behavior across pages, not individual visuals.
How to Configure Sync Slicers
Step-by-Step Process
- Create a slicer on one report page
- Select the slicer
- Open the View tab
- Enable Sync slicers
- In the Sync Slicers pane:
- Check Sync for pages that should share the selection
- Check Visible for pages where the slicer should appear
Sync vs Visible (Critical Exam Concept)
Each page has two independent settings for a slicer:
| Setting | Purpose |
|---|---|
| Sync | Shares the slicer selection with that page |
| Visible | Controls whether the slicer is displayed |
Key exam insight:
A slicer can be synced but hidden, meaning it still filters the page even though users cannot see it.
Common Use Cases
1. Global Filters
- Date
- Region
- Business unit
- Fiscal period
These slicers are often synced across all pages.
2. Context Preservation
Users select a customer on Page 1 and expect Page 2 to reflect the same customer automatically.
3. Cleaner Layouts
A slicer is visible on a landing page but hidden on detail pages while still filtering data.
Limitations and Rules (Exam-Relevant)
- Sync slicers work only at the page level
- They do not override visual-level filters
- Slicers must be based on the same field
- Syncing does not combine slicers — it links identical slicers
- Sync slicers do not work across different reports
Sync Slicers vs Other Filtering Options
| Feature | Scope |
|---|---|
| Visual-level filters | Single visual |
| Page-level filters | Single page |
| Report-level filters | All pages |
| Sync slicers | Selected pages, user-controlled |
Exam angle:
Sync slicers are preferred when user-driven filtering is required across multiple pages.
Best Practices for PL-300
- Use sync slicers for high-level context
- Hide synced slicers to reduce clutter when needed
- Label slicers clearly to avoid confusion
- Avoid syncing highly granular slicers unless necessary
- Test slicer behavior during page navigation
Common PL-300 Exam Traps
- Confusing sync slicers with report-level filters
- Forgetting that hidden slicers still filter data
- Assuming slicers automatically sync across pages
- Expecting sync slicers to work across reports
PL-300 Key Takeaways
You should be able to:
- Configure slicer syncing and visibility
- Explain when sync slicers are appropriate
- Identify synced-but-hidden slicer behavior
- Compare sync slicers with other filtering methods
- Improve usability with consistent filter context
