Net due date of the credit notes should be calculated as per the payment term

Issue: The net due date of the credit notes should be calculated as per the payment term of the customer account.

Reference field: Table BSEG & Field Name REBZG

We have checked and if the field REBZG is updated in accounting document number, then the net due date of the credit note will be calculated as per the payment term of the customer master data.

So, Kindly suggest Is there any option to update this field REBZG (invoice ref) through SALES ORDER OR BILLING ACCOUNTING DOCUMENT NUMBER to accounting document number.

Thanks,
