Use the agreed units, actual records and approved procedures for your operation.
A WORKED EXAMPLE
A net need and an order quantity can differ.
A planner needs 110 units but the agreed ordering multiple is 100. Under a round-up multiple rule, the proposed quantity is 200, subject to the other valid planning constraints.
