SAP Netweaver Business Intelligence BI / BW

Symptom

When executing large and complex workbooks (specifically in planning scenarios) in the BEx Analyzer, roundtrip times in a WAN environment can take very long.
Other terms

RFC TCP IP wide area network
Reason and Prerequisites

Due to the current data transport mechanism, too many roundtrips (both on the RFC and TCP/IP level) are executed in workbooks with a big number of data providers.

New parameters to activate/adapt improvements:
You can use transaction RS_FRONTEND_INIT to maintain the parameters below to activate/adapt the system behaviour accordinglyANA_USE_SIDGRIDWBUF
When set to ‘X’ (default after SP 5), this parameter will half the RFC roundtrips per data provider by combining 2 RFC calls into 1ANA_USE_SIDGRIDMASS
When set to ‘X’, there will be only one single RFC call for all data providers in a workbook.
Caution: this reduces the WAN overhead significantly but due to the need for the additional de-/serialization step could increase the CPU load both on the back- and frontend side.

In urgent cases the correction instructions can be used; please see
attached a tranport file with the needed DDIC structures.
