How to split a report and change the dataset?

Thanks mussaenda,

thats waht I was searching for. Could not imagine, that it is so easy.

1) I saved the original report as "Base"-Dataset

2) I created a new Report, using the "Base"-Dataset as (only) source

3) I copied everything with STRG+A -> STRG+V (page by page)

4) I had to re-set the report/page level-filters (but thats everything, formating and visual filters are copied)

5) I saved the file es "Individual1"-Report

6) I did the steps 2-5 for all pages/reports, I want to move

7) I deleted the reports in the "Base"-Dataset (which now contains only the connections and the row-level-security)

Many thanks, for your help. I still could not "exchange" the dataset, but is is so less work, that it is easy to handle (needed just once).

Best regards,

Thomas
