We are on S4 Public cloud and using AP Invoice IDOC process for posting Intercompany Invoice automatically once the Intercompany Billing is generated by Selling Entity.
However, we do not want to post the AP Invoice directly. We only want to park the invoice and trigger an approval workflow. We are unable to change the FM assigned to the IDOC type.
Please let us know how can we change the FM assigned to IDOC type (INVOIC02).
