Automatically provide user access to "Report A" based the access to "Report B"

Hi Miguel_Rojo 

In order for this to work, you'd have to put in some kind of automation for this process to work where you would have to specify the relationship between report A and report B. If you can put that relationship in place, you could then use the power BI rest APIs to see the access that a user has in report A and then grant that access file. The rest API to report B. You could use this doing something like power automaton. that would take a few steps to get it completed, but it could certainly be done.  Admin - Reports GetReportUsersAsAdmin - REST API (Power BI Power BI REST APIs) | Microsoft Learn
