Installing Application Component
Hierarchies
You use this function to install and activate application component hierarchies delivered by SAP or by partners.
After the DataSources are replicated in SAP NetWeaver BW, this application component hierarchy is displayed with the transferred DataSources in the source system view of the Data Warehousing Workbench – Modeling. Choose DataSource Overview (in SAP NetWeaver BW) by using the context menu (right-mouse click) for the source system.

If you activate the BI Content application component hierarchy, the active customer version is overwritten when you install the BI Content version.
For information about changing the installed application component hierarchy, see Editing DataSources and Application Component Hierarchies.
