Hi,
We created sales order with a wrong item code, then generated the prepayment invoice for 50%. Now we want to rectify the item code, but NAV 2013 is not allowing to change as prepayment invoice has been generated against it. Prepayment invoice is of Jan 2018, and we are invoicing the sales order in June 2018 and we dont want to generate a new sales order for this now. How to rectify this? Solutions would be a great relief.
