Answer:
What is the use of this?
Basically... if you have one record coming into your DataTarget (InfoCube A), but you wish to have more records in your DataTarget.
Don't have an example right here... played with it last year I guess. If I recall correctly we needed to add a record coming from another DataTarget (ODS B) per record that was fed into InfoCube A.
The problem (at least for us it was a problem) is that you need to have everything in that return table (even your characteristics).
