Financial Reporting: Base members of Current Point of View for Entity

Question

How do you typically handle reports in which you'd like to show all base members of the current point of view, but also allow the user to select a base entity?
Example A: Base members of Current Point of View for Entity
User selects a base entity: report errors
User selects a parent: report functions as expected and shows base entities
Example B: Base members of Current Point of View for Entity (Inclusive)
User selects a base entity: report functions as expected and shows the base entity
User selects a parent: report shows base entities (as expected), but also shows the parent entity (which we do not want to see)
I think the last case listed is what we want, but is there any way to just show the base entities? Like an advanced suppression option or something I'm missing.
Thanks.

Answer 1

Unfortunately, we don't have anything that uniquely identifies our base entities (close, but not all of them). However, the report does work as desired by using the following for entity, set in the advanced properties:
Base members of Current Point of View for Entity (Inclusive) AND Bottom of hierarchy Entity
This will allow the user to select either A) parent or B) base entity from the hierarchy and the report will show either A) base entities of the parent (not the parent) or B) the base entity.
Not sure why this works and all the other things attempted did not, but as long as it works. Also tried conditional formatting on Level, but that always threw a level 0 (for both base and parent).
