MRP areas

I need to plan sub-contract components differently, depending on the higher-level assembly they are used in. I thought of using a different MRP area, but have trouble making it work. The SPK for my assembly is 30 (subcontracting), I have created the storage location views in the material master, I have created an MRP area in the material master of my component, referenced the storage location, and have also assigned that storage location to the item in the BOM of my assembly. The MRP run doesn't direct the subreqs to the MRP area, they stay in the main plant MRP area. What am I missing?

    Dear,

    Check whether you have done this step

    MRP Area Segments in the Material Master

    Use

    In order to be able to assign a material to an MRP area, you have to create the MRP area segment for this MRP area in the material master.

    MRP with MRP areas for the material is not activated until an MRP area has been assigned to a material. If you have not assigned an MRP area to a material, that is, you have not created an MRP area segment in the material master, the material will continue to be planned in the plant MRP area only. If you have assigned an MRP area to the material, the system can plan it in the plant MRP area and in the assigned MRP area.

    Prerequisites

    You have defined the MRP areas in Customizing for MRP.

    Features

    You can assign a material to one or more MRP areas by creating a segment for each MRP area.

    In the following screens, for each MRP area, you can enter individual MRP and forecast parameters that are different from those defined in the material master at plant level:

    MRP 1

    Here, you can enter an MRP group and define the data required for the MRP procedure and lot-size calculation.

    MRP 2

    Here, you can define procurement data, that is, the special procurement key and the storage location in which the goods are to be received, in addition to an individual planning calendar and, if necessary, data for the net requirements calculation.

    Forecast

    Here, you can enter the Forecast Parameters if you want to forecast for the material in this MRP area. This is also possible if you do not forecast at plant level.

    Consumption values

    Here, you can enter historical Consumption Values for a material in an MRP area if you use forecast-based planning for the MRP area.

    You can delete the assignment of a material to an MRP area in the material master as long as no postings exist in that MRP area for the material. To do this, place the cursor on the MRP area in the Overview: MRP areas dialog box and choose Delete.

    Activities

    You can copy the MRP data of a plant segment or the MRP data of an existing MRP area segment when you create an MRP area segment for a material. To create by copying, proceed as follows:

    In the material master (view MRP 1, screen area MRP areas), choose the function key MRP areas.

    The Overview: Display MRP areas dialog box appears.

    Choose .

    The Copy with reference dialog box appears.

    Choose whether you wish to use the plant-level MRP data or the MRP data of an existing MRP area segment. If necessary, enter the number of the MRP area, from which you want to copy the MRP data.

    Enter the MRP area, for which you wish to create the MRP area segment, in the Destination MRP area field and choose Copy.

    The new MRP area segment is created and displayed in the overview list.

    Select the MRP area and choose .

    Check the MRP and forecast parameters that were copied and carry out any necessary changes.

    Choose Adopt.

    The Overview: MRP areas screen appears.

    Choose Continue again and save the material master.

    You can display an overview for all materials in an MRP area. To do this, you go into Customizing for MRP and choose the IMG activity Define MRP areas. Call up an MRP area by double-clicking and choose Material overview for MRP area.

    The system logs changes to the MRP area segments. You can display the change log by choosing Display change documents in the overview list for the assigned MRP areas. In the document overview, you can display the details for the selected document by choosing .

    Hi Bil

    As per the MRP concept, system assigns the dependent requirements to MRP area, only when the issue storage loaction of components determined in planning run(via BOM), same as defined at MRP Area of material.

    please explain your scenoria with some examples sothat we can understand in better way.

    regards
