Procedure: Cross-System Planning Situation (SAP Library - Material Requirements Planning (PP-MRP))

Procedure: Cross-System Planning Situation

Purpose

This process describes how you evaluate the MRP run for a material that is maintained in several systems, which means cross-group.

Prerequisites

You have given your plants unique descriptions across all systems

It is known which plant is managed in which system in your customer model

You have set the authorization to display MRP in all the systems involved

Customizing

In Customizing, you have created a layout that defines which information is displayed in which hierarchy. You create the layout using the Customizing menu path Production ® Master Planning ® Master Production Scheduling ® Evaluation ® Define Layout

You have set up a logical system in Customizing and assigned the dummy message type PRODPL to the logical partner system in the partner profile. This assignment is used to determine the target system and to transfer the data by means of synchronized RFC.

You define the logical system under Basic Components ® Distribution (ALE) ® Sending and Receiving Systems ® Define Logical System.
You define the partner profile under Basic Components ® Distribution (ALE) ® Modelling and Implementing Business Processes ® Partner Profiles and Time of Processing.

Process flow

When you start the evaluation, the system uses the customer distribution model to check which plants are in which logical SAP System.

The system checks in each plant whether the material involved exists. When this is the case, the MRP data required is requested by means of synchronized Remote Function Calls (RFCs).

If the system that is calling cannot access the required information (when no access authorization exists, for example), it logs an error, which you can display.

The planning situation is displayed on the screen. The report contains all MRP elements that are defined in the specified evaluation layout, for example production orders, purchase orders, sales orders, reservations, and warehouse stocks.
