Page-level filters in Power BI - Dashboard Guide

Dashboard Mode - Page-level filters

Business Question

How do sales and profit vary by product category and region, and how can we focus analysis on a specific year using page-level filters?

Sample Data

OrderID	ProductCategory	Region	Year	Sales	Profit
1001	Furniture	East	2023	200	50
1002	Technology	West	2023	300	80
1003	Office Supplies	East	2022	150	30
1004	Furniture	West	2022	400	100
1005	Technology	East	2023	250	70
1006	Office Supplies	West	2023	100	20
1007	Furniture	East	2022	300	60

Dashboard Components

KPI Card: Total Sales

Formula: Total Sales = SUM(SalesData[Sales])

Shows the sum of sales for the filtered data.

KPI Card: Total Profit

Formula: Total Profit = SUM(SalesData[Profit])

Shows the sum of profit for the filtered data.

Bar Chart: Sales by Product Category

X-axis: ProductCategory

Y-axis: Total Sales (using SUM(SalesData[Sales]))

Shows sales distribution across product categories.

Table: Sales and Profit by Region

Columns: Region, Total Sales, Total Profit

Measures:

• Total Sales = SUM(SalesData[Sales])
• Total Profit = SUM(SalesData[Profit])

Shows sales and profit summarized by region.

Page-level Filter: Year

Filter on Year column to select one or multiple years.

This filter applies to all components on the page, limiting data to the selected year(s).

+----------------------+----------------------+

+-----------------------------------------------------+
| Page-level Filter: Year (applies to whole page)     |
+-----------------------------------------------------+
    

Interactivity

The page-level filter on Year controls all visuals on the page.

When you select a year (e.g., 2023), the KPI cards, bar chart, and table update to show data only for that year.

This helps focus analysis on a specific time period without changing each visual individually.

Self Check

If you set the page-level filter to Year = 2022, which components update and what data do they show?

• All components update: KPI cards, bar chart, and table.
• Total Sales KPI: Sum of sales for 2022 rows (150 + 400 + 300 = 850).
• Total Profit KPI: Sum of profit for 2022 rows (30 + 100 + 60 = 190).
• Bar Chart: Sales by product category for 2022 only.
• Table: Sales and profit by region for 2022 only.

Key Result

Dashboard showing sales and profit by product category and region, filtered by year using a page-level filter.

Practice

1. What is the main purpose of a page-level filter in Power BI?

easy

A. To change the data model structure

B. To filter data for all visuals on a single report page

C. To filter data only for one visual on the page

D. To filter data across all report pages

Solution

1. Step 1: Understand the scope of page-level filters

   Page-level filters apply to all visuals on the current report page only, not the entire report.

2. Step 2: Compare with other filter types

   Report-level filters affect all pages, visual-level filters affect one visual, and page-level filters affect all visuals on one page.

3. Final Answer:

   To filter data for all visuals on a single report page -> Option B

4. Quick Check:

   Page-level filter = single page visuals filtered [OK]

Hint: Page-level filters affect all visuals on one page only [OK]

Common Mistakes:

• Confusing page-level with report-level filters
• Thinking page-level filters affect only one visual
• Assuming page-level filters change data model

2. Which of the following is the correct way to set a page-level filter in Power BI?

easy

A. Drag a field into the Filters pane under 'Page level filters' and select filter values

B. Write a DAX formula in the data model to filter the page

C. Apply a slicer visual and link it to all pages

D. Change the data source query to filter data

Solution

1. Step 1: Locate the Filters pane in Power BI

   The Filters pane has sections for visual, page, and report level filters.

2. Step 2: Set page-level filter by dragging field

   Drag the desired field into the 'Page level filters' area and choose filter values to apply to all visuals on that page.

3. Final Answer:

   Drag a field into the Filters pane under 'Page level filters' and select filter values -> Option A

4. Quick Check:

   Drag field to page filters area = correct method [OK]

Hint: Drag fields to page filter area to set filters quickly [OK]

Common Mistakes:

• Trying to filter page using DAX formulas
• Using slicers without linking to page filters
• Changing data source instead of filtering in Power BI

3. Consider a report page with a page-level filter set to show only sales from the year 2023. If a visual on this page shows total sales, what will the visual display?

medium

A. Total sales only for the year 2023

B. Total sales for all years in the dataset

C. Total sales for the year 2022

D. No sales data because page-level filters do not affect visuals

Solution

1. Step 1: Understand the effect of page-level filters on visuals

   Page-level filters restrict data for all visuals on that page to the selected filter values.

2. Step 2: Apply the filter context to the visual

   The visual showing total sales will only sum sales data where the year equals 2023.

3. Final Answer:

   Total sales only for the year 2023 -> Option A

4. Quick Check:

   Page filter limits data shown in visuals [OK]

Hint: Page filters limit all visuals to filtered data [OK]

Common Mistakes:

• Ignoring page-level filters effect on visuals
• Assuming visuals show all data ignoring filters
• Confusing page-level with report-level filters

4. You set a page-level filter on the 'Region' field to only show 'West' region data, but some visuals still show data from other regions. What is the most likely cause?

medium

A. The data model has no relationship between Region and sales data

B. The page-level filter was set incorrectly or not applied

C. Page-level filters do not affect visuals at all

D. The visuals have their own visual-level filters overriding the page filter

Solution

1. Step 1: Check filter application and visual filters

   If page-level filter is set correctly, it should affect all visuals unless overridden by visual filters.

2. Step 2: Analyze the scenario

   Since only some visuals show data from other regions, those visuals likely have visual-level filters overriding the page-level filter.

3. Step 3: Identify the root cause

   Visual-level filters override page-level filters, explaining why only some visuals are unaffected.

4. Final Answer:

   The visuals have their own visual-level filters overriding the page filter -> Option D

5. Quick Check:

   Visual-level filters override page-level for specific visuals [OK]

Hint: Check visual-level filters overriding page filters when some visuals ignore them [OK]

Common Mistakes:

• Assuming page filters never apply
• Ignoring data model relationships
• Not checking visual-level filters

5. You want to create a report page that shows sales data filtered by 'Product Category' and 'Year' using page-level filters. However, you also want a slicer on the page to let users filter by 'Region' dynamically. How should you set this up?

hard

A. Use only slicers for all three fields to allow dynamic filtering

B. Set all three fields as page-level filters to restrict data upfront

C. Set 'Product Category' and 'Year' as page-level filters; add a slicer visual for 'Region' on the page

D. Set 'Region' as a page-level filter and 'Product Category' and 'Year' as slicers

Solution

1. Step 1: Apply fixed filters using page-level filters

   Set 'Product Category' and 'Year' as page-level filters to restrict data for all visuals on the page.

2. Step 2: Add dynamic filtering with slicer

   Add a slicer visual for 'Region' so users can interactively filter data by region on the same page.

3. Step 3: Confirm filter behavior

   Page-level filters apply fixed restrictions; slicers allow user-driven filtering dynamically.

4. Final Answer:

   Set 'Product Category' and 'Year' as page-level filters; add a slicer visual for 'Region' on the page -> Option C

5. Quick Check:

   Page filters fixed, slicers dynamic [OK]

Hint: Use page filters for fixed, slicers for dynamic filtering [OK]

Common Mistakes:

• Setting all filters as page-level removes slicer flexibility
• Using only slicers loses fixed filter control
• Confusing filter scopes and user interaction
