Create a Custom Data Model for a Work breakdown structure (WBS)
This How To Guide describes the solution to create a custom flex data model for WBS. The reuse mode, which can be also used if the tables already exists in SAP S/4HANA, is not used in the guide. For simplicity reasons, the guide only describes using flex mode and does not include how to push the staging data to the backend tables. Download the DocumentPUBLIC
