I have an invoice coming from PSA to ODS. In PSA, the invoice has a Financial document number but invoice number field empty.When its loaded into ODS, the invoice field is geting populated with a value. What are the possible places where we can poulate a field between PSA and ODS?
As far as I know, a field could(object) could be populated at
1. Start routine
2. In transfer structure in update rules.
Are there any other places where the field can get a value? Actually there is customer exit for the data coming from R/3(for enhancements in extraction), which has a code for invoice number. But by the time the invoice comes to PSA, I think the field has to be popluated. Am I right? Or is there any mistake in what I am talking?
Any suggestions are appreciated.
