When a sales order contains sales prepayment, the user enters 'prepayment %=100", can decide to compress the prepayment or not, enters 10-50 lines for items, then posts prepayment invoice. The prepayment invoice looks good, has has numbers, amounts, prepayment %, etc. Then we received the incoming payment, apply the payment to a prepayment invoice and prepare to ship the goods. After the goods are shipped, we are ready to process the final sales invoice and here is a big issue where the majority of complaints arrive...
==> final posted sales invoice printout contains prepayment as negative lines inside the document lines (either grouped by VAT [compress prepayment] or reflect each and every line of the prepayment invoice [compress prepayment disabled, before posting sales prepayment invoice]. Therefore an unhappy end customer, who receives such a final invoice, makes our company very unhappy.
Please evaluate a possibility to calculate the posted sales invoice amount and VAT disclosure before prepayment in the final sales invoice, then create 1 line 'Prepayment made' to show the total amount applied to this prepayment invoice, afterwards show the document total "Remaining Amount" 0.00. This would make a lot of partners, customers and especially end customer more happier, when receiving the printouts from D365 Business Central.
