Carrying out the MRP Run (SAP Library - Production lot planning / individual project plann)

Carrying out the MRP Run

Use

During the MRP run, the system determines the material requirements that are needed to produce the production lot, and creates the necessary procurement elements with reference to the production lot (WBS element).

Prerequisites

In Customizing for MRP, in the IMG activity "Define BOM explosion control", you have set the indicator: Procedure with sales order/WBS BOMs active.

In the material master record of the material, for which you have created production lots, you have set the indicator to 1 in the field MRP dep.requirements of the MRP data. This indicator means that, during the MRP run, no receipt elements (planned orders, purchase requisitions and so on) are created by the system for the dependent requirements of the material (dependent requirements, dependent reservations, reservation requirements).

You have created planned independent requirements for the finished product or for the assembly with reference to the production lot (WBS element) in Demand Management.

Features

You can carry out a total planning run or a single-item, multi-level planning run.

The planning run creates dependent requirements for assemblies (with material type: HALB) for which production lots and planned independent requirements have been created. However, no receipt elements are created for these dependent requirements, as only the available planned independent requirements for the material are taken into account in the planning.

The work breakdown structure BOM, which you created for the production lot, is used for the BOM explosion in the planning run. If you have not created a work breakdown structure BOM, the system uses the material BOM.

The system creates procurement elements that are assigned to the account of the production lot (WBS element) for every BOM level of the material, which is designated to be planned using production lots.

An individual project segment is available at every BOM level for the production lot, which are then displayed in MRP Evaluations. The required quantities for the production lot are managed and billed as individual project stock.

Activities

In order to carry out material requirements planning, starting from the MRP menu, you choose: Total planing, Sng-item, multi-lvl or Sng-item project.
