Printing Wide Matrices and First-Page Header in Power BI Report Builder

prabavathym — Mon, 22 Sep 2025 12:33:25 GMT

Hi Community,

I’m working in Power BI Report Builder and facing two issues when printing/exporting to PDF (A4):

1 Matrix Pagination

My table has 20 rows × 40 columns, split across 2 pages with a page break.
Currently, PDF prints: first 10 rows × first 20 columns, then next 20 columns × first 10 rows, and so on.
Expected: print all rows for the first 20 columns, then next 20 columns with all rows (like Tableau).

2 Header on First Page Only

I want the header only on the first page.
Using header properties works in preview, but in PDF it still shows on all pages.

Any suggestions to achieve Tableau-like printing behavior in Power BI Report Builder?

Hi prabavathym,

Power BI Report Builder uses a "hard page" PDF renderer. When a wide matrix can’t fit, the renderer slices it into chunks based on page width and height. By default, the PDF will step through chunks in a fixed order (left to right, then down). There isn’t a built-in "print all rows for the first N columns, then move to the next N columns" toggle like Tableau. To get Tableau-style output, you force the page breaks yourself by grouping the columns into "bands" (e.g., 20 columns per band) and adding a page break between those bands. For the header, the safest approach is to either hide the page-header contents after page 1, or move the "header" into the report body so it appears only on page 1.

Quick solution

1) Matrix pagination like Tableau (all rows for first 20 columns, then next 20)

In your dataset, add a stable sort key for your dynamic columns (e.g., MonthStart, FieldOrder, etc.). Create two computed fields:
- ColIndex = row number over your column sort
- ColBand = 1 + (ColIndex - 1) / 20 (integer division)
Example (T-SQL):
```
SELECT
  ...,
  ROW_NUMBER() OVER (ORDER BY YourColumnSort) AS ColIndex,
  1 + (ROW_NUMBER() OVER (ORDER BY YourColumnSort) - 1) / 20 AS ColBand
FROM ...
```
In the Column Groups pane, add a parent column group above your existing dynamic column group, grouped on =Fields!ColBand.Value.
Select that parent column group and set a Page break "Between each instance of a group." Optional: set ResetPageNumber = True if you want each band to start at page 1.
Keep your current column group inside the band. Set header repetition as needed so row/column headers repeat across pages.
Docs: Add page breaks (group instances), Repeat row/column headers, Renderer support.

2) Show the page header only on the first page

Option A (fast): Keep the Page Header. Put all header content inside a rectangle. Set the rectangle’s Hidden expression to:
```
=IIF(Globals!PageNumber > 1, True, False)
```
This hides the contents after page 1. Note: the header space still reserves height on later pages (empty band).
Option B (cleanest layout): Remove the Page Header. Add a rectangle at the very top of the report body that contains your "header" content. Put a Page break after that rectangle so the main matrix starts on page 2. This way the header appears only on page 1 and no extra header space is reserved on later pages.
Docs: Hide header on first/last page. Example using Globals!PageNumber: Stack Overflow example.
