Requirement Types for Independent Requirements: LSF, VSF, VSE
(1) Can anyone explain the following requirement types in layman's terms:
LSF (Make-to-stock production)
VSF (Planning with final assembly)
VSE (Planning without final assembly)
(2) Upon transfer to demand management, how to determine which Requirement Type to use?
Requirement classes are created first and they are assigned to requirement type, further these requirement types are assigned to strategy. This strategy is assigned to material master. The strategy will decide how the Demand should behave during MRP run.
LSF ( MTS ) is used for MTS strategy 10 " Net requirement planning". So in this we will define through req class. The sale order is for display purpose only, The Sales order should not consume PIR. It is net requirement planning.
VSF ( MTS ) is used for MTS strategy 40 " Planning with final assembly". So in this we will define through req class. The Sales order should consume PIR. It is net requirement planning.
You should decide based on clients requirement which strategy should be used to ful fill the need of the client.
