Hi, Can we chnage the Serial No of the Item after posting of Sales Invoice (Direct Sales Inovice). Our Client’s Warehouse is at remote location and it is a very huge warehouse. They are not following any item stocking procedures like (Bin or Bay). Since they do not follow any stocking policy it is very hard to track and find the item serial no suggested by the system. The problem is they know the serial no of the item at the time of shipment ( it can be on any date) only. Navision does not allow to post the invoice with out selecting the serial no of the item. They want to post the invoice immediately after the creation to know the customer balance and the stock availability. Is that possible to enter serial no of the item after posting of sales invoice. regards, Sarukai
