DataSources for Business Object Associations
Use
CAF provides special DataSources representing associations between business object nodes. Each DataSource represents one association between two business object nodes.
Example
If we have two business object nodes:
and where the business object node Teacher has one-to-many relation with Subject called subjects.
sap.com/school/Teachersap.com/school/Subject
The DataSource that CAF would provide for the association between these two business object nodes contains the following characteristics: (assume that CAF_BI_DATASOURCE_NAME_PREFIX =
E41)
DataSource name: E41subjectsTeacherschoolfindBy
