BPC upload from BW infocubes

Hi yo all,

in my BPC application I have activated the upload of data from BW infocube (chain /CPMB/LOAD_INFOPROVIDER). The source infoprovider contain more dimensions that BPC application and so I have created an aggregate on BW infocube. My intention is to speed up the load in BPC.

I don't see any performance increase so the question is: BPC data manager uses the BW aggregates or is only able to read directly the infocube?

Regards

Stefano
