Thank you! I'm going to give this a try and see how it goes.

The issue isn't with creating the custom hierarchy. I can do that. The issue is that for the converted projects, their funding/revenue rows have task -99999, so in order for me to join the custom hierarchy to the funding/revenue rows, I have to join but both the task ID and the project ID. When I do that, OAC no longer…

Thank you, both, so much!!
