This will probably be easy points for someone.
I am processing an inbound customer master using the IDoc type DEBMAS02. When I process the IDoc through WE19 in the background (with debugging on), the customer is created - no problem. But then, the IDoc fails with status 65 stating that "Cross-system company code 0001 does not exist." Is there a piece of config that I am missing to set up the company codes?
