I was shown and told to use PO function to build supplemental and customer orders and always use supplemental as order type. SOR function is not turned on.
I do an order with part number "X" on it and send it. Later do a second order for a that also includes part number "x" I get a warning that part is already on order and to modify existing order.
The first order is already sent (thou is still modifiable).
So what are we doing wrong that first order is not final and why would system not allow separate order of same item?
