Trouble setting up RLS for a set of reports

[J_Melton_TX]

I couldn't locate where this issue was addressed, so I will ask here.  I am sort of new and having to learn things on my own, please forgive my lack of knowledge

We have a business with multiple locations and different owners/users that need to be limited to seeing details about their location, but NOT see the info for other locations.

I have a central PBIX file which pulls and cleans all of the data for all locations.
I have 2-3 PBIX files with sets of reports for various roles within the organizations that pull data from the central file, but don't store the data.
I will create apps from the various files which are accessible by staff at each location.
I am able to set up roles in the main file and restrict those roles to only see a particular location's data.

My issue is that I cannot set up those roles in the other "report" files.  That option does not appear in the same place it does on the central file.   I don't know if the RLS will work "through" the secondary PBIX file where the reports are.   I also don't see where I can assign those roles in the resulting apps from those report-centric PBI files.

I am more than a little past my experience level on this.  Any help would be appreciated.  Thank you!

Thank you.   This is very helpful - back to the computer!

RLS only works on datasets. Your "thin reports" are just the report layer back to the original dataset. You need to create all RLS rules on that golden dataset. The thin reports will all honor those settings.
