Connecting Expense Receipt & Assigned Approver in a Custom GI

Thanks @BenjaminCrisman.  I was able to join the EPExpenseClaimDetails with the EPApproval with an inner join and with the noteID and refNoteID relations as you suggested.  We have a 2 step approval process for our expense receipts so I did need to do some conditioning with the fields so I only saw 1 record per expense receipts but I think I have it figured out.  Would there be a way to join the tables and use conditioning in the relations of the tables to only see 1 line in the results grid for the first approval that is pending?  An example would be when the first approval step is pending, it would show that assigned approver and after the first approval is complete, the line would then reflect the second assigned approver?  What I am asking for is what I am accomplishing with my condition on the GI (ApproverID is empty) but once the approvals are done, the receipt will disappear from my GI because it no longer meets the condition that “ApproverID is empty”.

@BenjaminCrisman Thanks so much for your reply.  That was super helpful.  I wanted to be able to see 1 line for every expense receipt regardless of the status.  I took what you did and expanded on it.  Here is a snapshot of what I ended up with for my conditions.

I was able to use the StepID descriptions to filter out the lines that I wanted for the Open and Released Statuses.
