Both the client installation & the BIP Add-on for Analysis for Office on our system is on 2.1 SP2.
Due to a pretty big performance-bug, oss note 2224555 (http://service.sap.com/sap/support/notes/2224555) advises to install 2.1 SP3 of the client tool.
We did this, and the performance bug indeed seems to be solved.
Now, the question: should we also upgrade the SP of the BIP addon? I see that both SP's are released in sync date-wise, so they look to be connected, but the test without the BIP Addon SP installed worked, so it doesn't seem necessary...
Any thoughts?
