We have a requirement where two accounting documents needs to be created for a single invoice as per client requirement. We have managed to achieve this using Billing user exit. Now, we want to link the two accounting documents under the billing document.
Scenario is as below.
Billing Type: ZFx
Accounting Document Type in Billing Type: AB
Additional Accounting Document Created: XY
Now, in the document flow, we need both AB & XY documents to appear under the billing document.
Can you help to let me know how to achieve this?
Many thanks in advance.
