We have a strange situation where an order was made up and a pick slip generated and posted. When the order was filled an invoice was made and posted. After we ran end of day I noticed the invoice was not on the customers account. It does not show up on the end of day and is nowhere in the system that I can find. There was no credit note done to cancell this invoice.
But I have the printed copy of the invoice. The order shows up in the customers file as being filled. Does anyone have any suggestions as to what could have happened? I have checked the dates on the invoices and they are correct, 02/10/2009.
