Vendor requested for 100% prepayment.
Prepayment invoice has been created and posted and paid for 100 EUR.
Now, goods are received and in the final invoice vendor gave a discount and sent final invoice for 80 EUR.
80 EUR final invoice is settled with 100 EUR prepayment invoice leaving an open prepayment of 20 EUR.
For rest of the 20 EUR vendor sent a credit note.
This resulted in 2 open transactions first being the credit note and second being the open prepayment.
Credit note will do into payment proposal and the net payment amount will be corrected accordingly so no issue here.
How to clear off the 20 EUR in "open prepayment" form?
