- Customer has recevied an order made up of 5 lines of items.
- Customer is on account so has not paid for order yet.
- Customer has returned one line of items.
- I create a return delivery note to reintroduce stock to shelf
- Return Delivery Note requests serial numbers
- Inputted serial numbers changes quantity from a negative value to a positive value
- Return DN won’t submit with a postive value or without serial numbers.
How can I resolve?
Have I approached this wrong?
