how to improve the report performance?



how to improve the report performance?..

Answer / kumar

1) Try to use the less no. of Queries& Outer Joins.
2) If any calculation are used frequently, that need to do
at ETL level since data will be loaded with taht
Calculation.
3) avoid the Joins at Report Level.
4) Remove the unwanted Columns @ Report level.
5) Adding filters to reduce the amount of data to perform
the report well.
6) if we are using any specific filters for mutiple report
we need to create that filters at FM level as Stand alone
Filters.
7) We prefer Drill through to Master Detail Report to
reduce the time taking.
8) We prefer Conditional block to Render Variable for
Performance.
9) Use Local Cache ,If we run the any Report Frequently it
will reduce the Time.

Thank You
