Wayne, I ran into something like this earlier this year. I do not remember the exact details, but I believe I determined that in the RA_ReturnDetail file there were records that had ""00"" for the APDivisionNo, but no value for the VendorNo and this was causing the SO not to be created. This particular customer did not have RMA integrated with the PO module. Before they create the next RMA receipts entry, find out what the RMA number is and check out the RA_ReturnDetail file and see if there is a value in the APDivisionNo, but no value for the VendorNo. If so delete the ""00"" from the APDivisionNo. Then have them process the RMA return and generate the transactions and see if the SO is created. If this does not make sense, feel free to give me a call.
