This activity is used to pick-report a supplier shipment. Once a supplier shipment is reserved, it needs to be picked from the specific locations. You cannot report-pick with differences with the supplier shipments. Furthermore, during rental returns, If you have reserved a partial quantity out of what has been originally planned to return, then while picking the planned quantity to be returned will be reduced to match the picking quantity. If you have incorrectly reported the supplier shipment as picked, then you will have to cancel the whole shipment and start the process from the beginning.
