Thank you all for your replies. I am now able to successfully route the Advance Payment through F-47 and F110. However, I have the following query.
1. Once the payment run is executed through F110, we see a Debit on Vendor Books in Special Indicator Items as a ZP Document, so even if we do not cancel the Pre-payment Entry through F-54 ( which moves the Debit from Special GL to Normal Items), the chance of double payment is eliminated as the Debit is already posted and even if we post the Invoice without payment block, the Debit & Credit will get knocked off ?
Is my understanding correct.
