Characteristic relationship using plannable DSO

Hi,

I am currently trying to build characteristic relationship for a plannable DSO.

Therefore I would like to use a second DSO (also plannable) to determine valid combinations.

Thus the system does not let me use a plannable DSO (transactional DSO not allowed) in my characteristic relationships.

I have seen this construct being accepted by a BW 7.40 system thus my customer used BW 7.30.

Any idea why the system does not allow me to use plannable DSOs in characteristic relationships?

Thanks,

Julian
