I am populating a few custom segments using a BAPI in the customer and vendor master outbound user exits. I need to fail the IDoc, if the BAPI returns an error. The user exits EXIT_SAPLVV02_001 and EXIT_SAPLKD01_001 does not have the idoc status table passed to it as a parameter. Does anyone know of any other user exits that could be used for modifying the idoc status. Thank you for your response.
