Data Manager - what exactly is/does that?!

[marco_simon2]

Hi Specialists,

while checking my BW query times (using the technical content / statistics) I realized that the absolutely majority of time is spent for the "data manager".

So the next question was: What's the "data manager"? What is its function and how can I get more detailed information about the time-usage. How can I reduce the time needed in the "data manager"-step.

Could you please gimme some hints or links about that topic?

Searching the help.sap.com and the sdn (using the keywords "performance" and "data manager") didn't bring me far.

The Data Manager step in BI Statistics or an RSRT trace represents the database read time from your infoprovider. There are a number of ways you can improve this performance step (search for OLAP caching, aggregates, or BI Accelerator).
