MM-MRP query

Dear All,

1) If we keep Collective requirements only (2) rather than Blank or 1 in MRp4 then what will be the impact on Purchase & MRP Run

2) What are the configurations needed at SPRO level for automatic generation of PR during MRP run?

Regards,

Indranil

    Hi Indranil,

    1) Please read F1 help for field MARC-SBDKZ:

    Dependent requirements ind. for individual and coll. reqmts

    Indicator determining whether the following requirements are allowed for the dependent requirements of the material:

    Individual requirements

    Requirement quantities of the dependent material are stated individually.

    Collective requirements

    Requirement quantities of the dependent material are grouped together.

    Use

    You can maintain this indicator in the following places:

    In the material master record

    For the explosion type of the BOM item (in Customizing for Basic Data in Define Explosion Types)

    The setting for the explosion type overrides that in the material master record.

    Dependencies

    If the material is assigned to a material type that does not allow quantity-based inventory management in this plant, you can set the indicator to individual requirements only.

    If the stock is to be managed in sales order stock or project stock, the indicator must be set to one of the following options:

    Individual and collective requirements

    Individual requirements only

    If a material managed in project stock is to be procured from another plant using a cross-company-code stock transport order, the indicator must be set to 2 (collective requirements) in the issuing plant because, in this specific context, individual project stock management is not possible in both plants.

    E.g. if you are in MTO environment and you use 1 in this field (of the component) then the dependent requirements (of the component) are generated in special stock segment of MRP. In case of value "2" dependent requirements will be generated in the "main" (e.g. plant) segment of MRP.

    2)

    - You have to maintain the proper procurement type in MARC-BESKZ ("F") /or if you use quota arrangment, then in MEQ1)

    - You have to run MRP with proper selection paramters (e.g. 1-3-1-3) in MD01 / MD02 / MD03 - Please check creation indicator, F1 help:

    Creation Indicator for Purchase Requisitions

    For materials procured externally, this indicator controls whether the system:

    creates purchase requisitions for the total planning horizon,

    creates planned orders for the total planning horizon which are manually converted into purchase requisitions at a later date,

    creates purchase requisitions within the opening period and planned orders outside the opening period.

    Dependencies

    In the single-item planning run, the system always uses the creation indicator specified in the initial screen of the planning run. The creation indicator maintained in the MRP group is not taken into account.

    Regards,

    Csaba
