Grouping WBS elementA Grouping WBS element is a WBS element that has valuated project stock on which the requirements from several WBS elements are grouped together for materials requirement planning (MRP).
You determine that a WBS element is a grouping WBS element by making the following settings for the Grouping WBS element
field on the WBS element detail screen (on the Basic data
tab page in the standard system)
If this WBS element is to be the grouping WBS element for all components assigned to the WBS elements that have been assigned to this grouping WBS element, enter Grouping WBS element for all materials
(1).
If the material components assigned to a WBS element are to have different grouping WBS elements, enter Grouping WBS element for selected MRP groups
(2). This could be the case, for instance, if you want to plan electrical and mechanical parts separately.
The valid grouping WBS element is then selected on the basis of the MRP group and plant of the material.
