Assigning DataSources to InfoSources and Fields to InfoObjects 
Use
You carry out the assignment of a DataSource to an InfoSource in the BW transfer rules maintenance.
In the DataSource overview for a source system in the Administrator Workbench – Modeling, there is also the additional option of assigning an unmapped DataSource to an InfoSource. To do this, using the context menu (right mouse button) of a DataSource, choose Assign InfoSource. If you use this assignment option, you can
Assign several DataSources to one InfoSource, if you want to gather data from different sources into a single InfoSource. This is used, for example, if data from different IBUs that logically belongs together is grouped together in BW.
The fields for a DataSource are assigned to InfoObjects in BW. This assignment takes place in the same way in the transfer rules maintenance.

For Business Content DataSources, the assignment to InfoSources, as well as the assignment of fields to InfoObjects, is delivered by SAP.
