We want to do an AR posting against a customer number through IDoc WPUFIB sent from POS DM. There's no field for customer number in this IDoc. We are sending customer number in extension segment E1WX001. Can anyone please tell us how to do this posting in ECC?
We know that WPUFIB can be used to do a posting against a cost center. It's unclear as to how we can do this against a customer number. Thanks!
