I have not been able to configure RBA for the following scenario that I would assume should be common:

Collections:

All Firm PCs

All Firm PCs (limiting Collection) > NY PCs

All Firm PCs (limiting Collection) > LA PCs

So we have administrators that should be able to see all PCs at the top level and have the "All Firm PCs" in the scope.  Then we have admins that should only see NY PCs, and LA PCs so their scope is only the "NY PCs" or "LA PCs". This works fine.

The issues is that for task sequences deployed to the "All firm PCs" collection, those in the NY and LA scopes cannot report on the advertisement that is applying to computers in their scope since the deployment applies to a collection outside of their scope.  Ideally, they should be able to report on the deployment for the PCs in their scope.

I have spent months on this so please help! Thanks!!

Exactly what report are you using?

Standard reporting.  For example, if you try and run "Status summary of a specific task sequence deployment" against a Collection in their security scope, they don't have any global deployment options in the dropdown.

Any help?

Yes, I know this is an old post, but Im trying to clean them up. Did you solve this problem, if so what was the solution?

Since no one has answer this post, I recommend opening  a support case with Microsoft Customer Support Services (CSS) as they can work with you to solve this problem.
