Hello,
I’ve issued a prepayment based invoice for a customer order, after it finalized the CO and made the final invoice - which considered the Prepayment Based Invoice in order to calculate it.
However we found a problem regarding a VAT code in one of the lines and have to create a RMA and a credit note to the final invoice and also be able to use the prepayment based invoice once again to match the final invoice.
Does anyone knows how to “de-tach” a Prepayment Based Invoice from a Final Invoice?
