Planning File Entries for MRP Areas 

Use

In order for material requirements planning to be carried out for an MRP area material, an entry must exist for the material in the planning file. If changes are relevant to MRP, the system must set a planning file entry.

Prerequisites

You have converted the planning file entries at plant level to planning file entries at MRP area level.

Features

Creating/ Changing / Deleting Records in the Planning File

  • If you assign a material to a new MRP area in the material master record, a new record is written in the planning file for this assignment.
  • If you change settings in the MRP area for a material that are relevant to MRP, for example, the MRP type, lot-sizing procedure and so on, the corresponding record in the planning file is changed, that is, the system sets a planning file entry for the MRP area material.

Setting a Planning File Entry

If you change MRP elements, the system checks the Plant, Storage location and Vendor (subcontractor) fields and determines the MRP area affected according to the MRP area assignment in the material master and the settings in Customizing. The system then sets a planning file entry for the material at MRP area level in the planning file.

During this process, the system decides whether the planning file entry has to be set for just one MRP area or for all MRP areas.

  • If you change a purchase requisition, the system determines the MRP area affected and sets the planning file entry for just the MRP area affected for the material.
  • If you change the BOM of a material, the system sets the planning file entries for all MRP areas of the material, as a change in the BOM has an effect on all MRP areas that are assigned to the material.
