We have a webi report that has 35 queries. We want to be able to have 10+ concurrent access to this report. However, only 10-20% of execution are successful.
In the document "How to performance optimize SAP BO reports based upon SAP BW" , we can read:
What is the effect of having many Bex queries in Web Intelligence?
... multiple Bex queries in a Web Intelligence report will consume from pool of maximum connections
Where do we change this pool of maximum conations in BW?
BTW, we already increased this parameter in DSL Bridge based on SAP Note 2034209: -Dco.cpic_maxconv=1000
