    Hi,

    You have misunder stood a little bit. The value stored in the table will be used with query which the user will run and that query will have dynamic filter value which will be the value from that table.

    Which means it will acts like global filter for query/query's

    Hope this helps !!!

    Hi,

    Let say you have 100 millions worth of data and user wants to query for sales for top ten customer then you can think of the performance problem that the user will face.

    What to do? User Precalcuation concept where using your information broadcasting you run the query after your loads in bw is finished and store that value in the table.

    Now when your actual query runs then the values will be picked up from the table which will be only those top ten customer which will be passed to the actual query which the user runs.

    hope this helps!!!
