Process documentationSegmentation: Material Requirements Planning (MRP) Locate this document in the navigation structure

 

The main function of material requirements planning is to guarantee material availability. That is, it is used to procure the requirement quantities on time both for internal purposes and for sales and distribution. This process involves the monitoring of stocks and, in particular, the automatic creation of procurement proposals for purchasing.

The material requirements planning process has now been enhanced to guarantee material availability at segment level.

The enhanced process uniquely assigns requirement quantities to available stock using segmentation values and / or creates procurement proposals, such as purchase requisitions, at segment level for nonexisting stock. The system determines the requirement segment in the proposals based on the rules defined in the segmentation strategy.

Prerequisites

  • You have maintained the transaction MD01N in the table PPH_HANA_ACTIVE so that you can use HANA DB

  • You have maintained the user parameter HANA_ACCESS = 02 in the user profile using transaction SU3

Process

For materials with segmentation, the system executes the planning processes based on the following mapping rules defined in Customizing for Define Segmentation Strategies under   Logistics – General   Segmentation  :

  • Requirement/Stock Allocation

  • Stock Transfer

  • Requirement to Stock Conversion

  • PIR Consumption
