Hi all,
as this thread helped me a lot during testing of 2.1 SP2 to find out that this is a version which is not usable from customer side. I received also a preliminary version of SP3 through an SAP Incident, because SAP BO Analysis 1.4, 2.0 and 2.1. ignores the processing priority when using BW-IP:

Another functionality which was not supported by the "premium alternative for the BEX Analyzer".. 
I keep my fingers crossed for 2.1 SP3 
BR,
