        ) ON COLUMNS FROM (
        SELECT
            STRTOSET(@CacheAttendeesConferenceId) ) ON COLUMNS FROM [Cube_Attendee])
        WHERE ( IIF( STRTOSET(@CacheAttendeesConferenceId).Count = 1, STRTOSET(@CacheAttendeesConferenceId), [Cache Attendees].[Conference Id].currentmember ) )
CELL PROPERTIES VALUE, BACK_COLOR, FORE_COLOR, FORMATTED_VALUE, FORMAT_STRING, FONT_NAME, FONT_SIZE, FONT_FLAGS
I want to filter my cube with three parameters
1. @CacheAttendeesConferenceId
2. @FromCacheAttendeesInsertTimeStamp
3. @ToCacheAttendeesInsertTimeStamp
When i pass following parameters
ConferenceId = 1, StartDate='2010-01-28T00:00:00', EndDate='2010-02-03T00:00:00'
Then it show records
But When i pass following parameters
ConferenceId = 1, StartDate='2010-01-27T00:00:00', EndDate='2010-02-03T00:00:00'
Then it display message No Data Available
PLease help me on this issue why not FromDate & ToDate range works properly.

Answer 1

Step1:- First i create a SSAS datasource. Then i create a cube for my table CacheAttendees.
It has following columns:-
[Cache Attendees].[Conference Id]
[Cache Attendees].[Group Date Count]
[Cache Attendees].[Insert Time Stamp]
[Cache Attendees].[Screen Name]
[Cache Attendees].[User Id]
[Cache Attendees].[User Type Id]
[Cache Attendees].[User Type Name]
[Cache Attendees].[Visit Id]
Step2:- Then i create a dimension with this cube with all columns.
Step3:- Then i deploy my SSAS project.
Step4:- Use SSAS datasource in my SSRS datasource.
Step5:- Create a report with chart control. Add a parameter ConferenceId. Set default to 1. When i preview my report then it show Cache Attendees].[Conference Id].[1] in header of report instead of that, When i pass the parameter value as 1 then report cannot show & throw an error. I want to pass this parameter at runtime.
Step6:- Please help me how is it possible to pass parameter at runtime.
