Hello,
we use BW on HANA and I try to connect our BusinessObjects Explorer 4.0 to this Database. I'm only from the basis team, not the bw team. 
The connection is already established vie the Information Design Toll and the Infocubes are easily prepared for the explorer. I'm able to view a list of all cubes in explorer but if I try to view them directly some privileges are missing.
Is there a guide outside with some best practice to manage this issue? Is it the best way to create a db user for every user of the explorer? Which privileges are needed?
best regards
Patrick
