Hi,
Surrogate are System generated sequential Values.
We use these keys to maintain the Historical data in EDW&
to set up relationship between Dimension Table & Fact Table.
It plays a key role in Maintain Historical data in EDW.
We prefer these Keys Even we have the Primary key Columns
in the Tables, since a customer may purchase several times
in a single day irrespective of time & Bill No. are
different.
In this situation we take these keys that give different
No. for several times Purchase in a single day.

Can someone tell me whether we can apply filter on list of values in the 'Value Prompt'? e.g. I have a value prompt (named city) and the prompting is holding around 2000 cities but I want to apply filters on cities so users can select only 15 cities out of 2000 and then run the report. Users should be flexible enought to select any 15 cities from the list. Is it possible. Please advice!
