Requirement Types for Independent Requirements: LSF, VSF, VSE

[Former Member]

Hi,

(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?

Thanks.

Hi Ling

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.

Hi,

The requirements types are, technically speaking, texts that represent the planning strategy in the application (Demand Management, Sales and Distribution).

The requirements type is associated with the requirements class.

The requirements class contains all the control parameters required for Demand Management and SD

Planning strategies are defined in Customizing by a combination of requirements types from Demand Management and from SD

This combination of requirements types determines, for example, the consumption of planned independent requirements by customer requirements, or how the availability check is to be carried out.

Hi,

Requirement type determines the following points:

1. Consumption of Independent req & customer req.

2. How warehouse stock taken into account.

3. Make to order or Make to stock.

4. Planned order can be released or not.

Requirement class is assigned with requirement type.

PIR requirement type & customer requirement type both linked with Strategy group.

Ex: For strategy 10, PIR req type is LSF & Customer req type is KSL.

So transfer to demand management in the material master if strategy 10 is assigned, system will take req type as LSF.

Same as if strategy 40, req type VSF

For strategy 50, req type VSE.
