R47071 Inboucd Receipts

We are using the SO / OK intercompany processes. We want to automatically recieve them OK's. I thought the best way was to use the R47071. I was going to create a UBE to populate the inbound file then just let it run. Before I right the custom program, I wanted to test it all first. I have an OK that is ready for receipt. I manually keyed in the data and ran the R47071. I am getting an Error in my Work Center saying that a UDC value is invalid. I have gone through every field and they all looks okay. Anyone have idea;s on which field it might be trying to validate. It occcus during the F4312Edit doc so it is tough to debug.

Meanwhile I will continue to test each field.

Thanks
