Role filtering vs slicer behaviour

[pntlindsay]

Hi,

I am hoping someone can help.  I have a report where roles are defined based on a field called territory.

I have some values that I dont want to be filtered by territory and these are calculated as follows:

team actual = calculate(distinctcount( total sales), all ('territories' [territories]).

I have a filter based on territory and when I select a specific territory I get "team actual" as I expect, without being filtered by territory. All good so far.

I now define Roles with a filter based on Territory.  When I select a role, I now get "team actual" filtered by the territory!  Which is not what I want.  

I cant understand the difference in behaviour.  What am I missing here please?

My understanding of row level security is once you define a role on territories, the underlying data for the team that is based in that particular territoriy will be 'visible', anything else is not accessible due to RLS working behind the scenes.
