To plan supply with master planning

When you use master planning to plan supply, LN generates a supply plan for the item's master-planning horizon. This is done in a master-plan simulation, by using the Generate Master Planning (cprmp1202m000) session or the Generate Master Planning (Item) (cprmp1203m000) session.

Infinite planning assumes that there are no capacity or material constraints. In workload control, capacity constraints and/or material constraints are taken into account.

If you want to use workload control, you need to define plan units. A plan unit groups items that use capacity at the same critical resource, or use the same critical material.
