The add-on installation does not contain any client-dependent customizing. Instead, the delivery includes a series of SAP Business Configuration Sets (BC sets) which are activated in the customizing client of the development system in order to initialize the customizing included in the package.

For more information on BC sets, refer to online SAP documentation such as the following:
