Deriving the Hierarchy from the WBS Element Numbers

Description

The hierarchy of a work breakdown structure can be automatically derived from the numbers of its WBS elements. You can enter new WBS elements at level 1 and then arrange them in the work breakdown structure by choosing Project-> Derive structure -> Execute. The WBS element with the shortest number is placed on level 1. Every further WBS element is then arranged in the subordinate hierarchy levels according to its number.

Example

Editing screen: P-XXX-XX-XX

WBS element number Level superior element
P-001 1
P-001-AA 2 P-001
P-001-AA-01 3 P-001-AA

If the hierarchy cannot be derived, the system ask you to check the structure. Choose Project -> Derive structure -> Check and you receive a message that gives you the reasons for the error.

Change system parameters in customizing

The prerequisite for deriving a hierarchy is that you have maintained an editing mask in Customizing for the project definition and its WBS elements.
