We have to process EDI 810 Invoice.We are using INVOIC02 idoc with custom segments. Which FM or process code I need to use for my requirement? Is it INVL or INVM or INVF?
What is the best user exit to to perform the validations based on custom segments and to update the frseg tables???
Also I need to park the invoice, whenever there is a duplicate invoice and based on some other validations (like quanity check /amount check)!!! Is this something configurable or how do I achieve this? If not configurable, do I need to perform this validations manually with in a IDOC and call BAPI to park the invoice?
