    Hi,

    Go to SE38 and run sap_infocube_designs and start checking each infocube. You will get how much data is there as well as fact table and Dimension table sizes. If you see dimension table is more than 20% of fact table then you can say high cardinality. Once you get that there were different techniques to improve query performance.

    Thanks

    • Hi Still,

      Follow the suggestion provided by others ..One more thing if you know your query is showing data from perticular perticular cube then fileter that infoprovider at query level.

      To improve performance your consider following points also

      1)provide as much selection to users

      2)do not use exclude in query designer etc...

      hope it will improve your query perforamance.

    Hi,

    In RSRT, Use Execute + Debug option and select BI Statistics. This will show you where exactly the query is taking time.

    Thanks,

    Hi,

    find the query run time at ST05 -> give the use name and activate the trace and run the query.

    now check the select statement.

    based on the you can create the aggregates and make it as the line item dimension.

    check the program SE38 - SAP_INFOCUBE_DESIGNS.

    check the which dimension have more than 20% based on you can make it as the line item dimension.

    first check with the aggregates after check it line item dimension.

    Thanks,

    Phani.
