X3 V12 here. Toying with use of Prepayments in SO module and in my testing I can see that when a sales invoice is created from a SO where a prepayment has been made, the prepayment doesn't appear until the invoice is POSTED. Our current business process is that we auto-email invoices to customers in the morning and then we post them later in the day. So, a customer would end up getting an invoice reflecting an incorrect balance. I'm sure the easy answer in your mind is to just post everything before we email it out and you MIGHT even say that is best practice. However, has anyone found a way to show the prepayment on the invoice BEFORE posting? Maybe just some Crystal magic is needed of the formulas for the balance?
