Hi,
just figured out, that the same effect occurs when executing on the BI platform.
But this might be related to configuration of the BI platform as described in chapter 5.3.6 in the Admin Guide for DS 1.5 SP1:

EDIT on 27.1.16:
Configuring the maximum cells for the result set on the BI platform, e. g. to 1.500.000 successfully gets propagted to the BW system with the same value, when executing the DS applications on the BI platform.
