example
i have a sales order with 2 lines
1 line for a botlle with quantity 1
1 line for return bottle with quantity -1
when i save the quotation, the demanded quantity is automaticly changed to 0
1 - 1 = 0
this results in a picking move that is automaticly cancelled becasue the demand quantity is 0
but this has to stay a 1 or 2 ( depending on how many ordered) because we have to send these bottles to the customer and wait for return
can someone help?
You should use different products for the full and the empty bottle.
