Receivables Aging by General Ledger Account Report pull in the actual Receivables GL Account Code

Summary:

For our audit needs, we have to be able to prove out that our Open AR balances align with our Receivable Control accounts at the GL Account String not just at the Natural Account.

After looking deeper into the Receivables Aging by General Ledger Account Report, it was determined that the FLEX_TYPE_INV is populating incorrect GL Account codes, how can this get updated to be based on the open AR transaction Receivables GL Account String?

OR is there a different report we should be running to get the actual GL Account String for the Receivable Class of the AR Transactions?
