Multi-Plant Requirements Grouping with Grouping WBS Elements 

Use

You use this procedure if you would like to combine material requirements using several grouping WBS elements. At the same time, you can use these grouping WBS elements in all plants.

The use of several grouping WBS elements makes sense if you want to form different groups across plants.

Certain WBS elements of sales orders from Europe are to be assigned to the grouping WBS element 1 in all plants and certain WBS elements of sales orders from USA are to be assigned to the grouping WBS element 2 in all plants.

Prerequisites

  • You have defined that a material is to be planned using requirements grouping by entering the appropriate MRP group in the material master.
  • You have entered a period lot-size, for example MB for monthly lot size, in the material master.
  • You have created several grouping WBS elements and have entered the indicator 1 the grouping WBS element field for them.
  • You have selected the Valuated stock field in the project definitions of the WBS elements and the grouping WBS elements (tab page Control data).

Features

In material requirements planning, every material that is allowed to be planned with requirements grouping, is planned with the grouping WBS element that has been assigned the WBS element, which has caused the material requirement.

Example Data

  • Material A is allowed to be planned with requirements grouping.
  • Material A is assigned to the WBS elements E1, E2 and E3 in the networks.
  • You assign the WBS elements E1 and E2 to the grouping WBS element D1. You assign the WBS element E3 to the grouping WBS element D2.

MRP Procedure

The requirements for material A that have been caused by WBS elements E1 and E2 are combined using the grouping WBS element D1. To cover these requirements, the system creates a procurement element (planned order or purchase requisition) that is assigned to the account of the grouping WBS element D1.

The requirements for material A that have been caused by WBS element E3 are combined using the grouping WBS element D2. The procurement element is assigned to the grouping WBS element D2.

In MRP Evaluations, the two grouping segments for the WBS elements D1 and D2 are displayed with the corresponding requirements and receipt elements for material A.
