| To plan supply with master planning |  |
| When you use master planning to plan supply, ERP 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. A supply plan consists of: Production plan Purchase plan Planned distribution orders (serving as a distribution plan ) In master planning, two methods for production planning are available: Infinite planning Workload control 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.
