Thanks everyone. But just to make sure I'm clear (and maybe help someone else) If one of the UDFs on the SO_SalesOrderDetail table is a UDF called CASES. If I want to print that UDF on the Sales Order, SO Invoice and from AR History, I will need to add that UDF to 1) SO_SalesOrderWrk, 2) SO_Invoice, 3)SO_InvoiceWrk, 4) AR_InvoiceHistoryDetail and 5)AR_InvoiceHistoryWrk? @BethBowers are you suggesting that I also need to modify some posting routine to get the SO_Invoice UDF to write to the AR_InvoiceHistoryDetail table?
