Error when adding a serial number to a sales order line


I get the following error when trying to add a serial number to a product on a sales order line.

The sales order has a reference to a purchase order which was created from the sales order.

The warning message i receive tells me to use the inventory button to remove the marking on the order line but when I navigate to Inventory > Marking there is no possible action to make.

What could cause this problem and how can it be fixed? I am thankful for any type of advices I can get [emoticon:c4563cd7d5574777a71c318021cbbcc8]

You need to change the quantity in the marked now field to -8 to unmark the already marked amount. Does that work?


Try to create serial number on related PO and select on drop down other wise go to line details unmarked it

“Why” are you trying to add a serial number to the sales line, when it is linked to an inbound Purchase Order?
