Add a page break to a Report Builder paginated report
Applies to: 
Microsoft Report Builder (SSRS)
Power BI Report Builder
Report Designer in SQL Server Data Tools
You can add a page break to rectangles, data regions, or groups within data regions in paginated reports to control the amount of information on each page. Adding page breaks can improve the performance of published reports, because only the items on each page have to be processed as you view the report. When the whole report is a single page, all items must be processed before you can view the report.
Note
You can create and modify paginated report definition (.rdl) files in Microsoft Report Builder, Power BI Report Builder, and in Report Designer in SQL Server Data Tools.
