How to retrieve Top 3 records in the group level

Hi all,

I have a report which is grouped by a field called R_ID, which gives me a list of records for each R_ID. So here is the thing, I want to get only top 3 records for each R_ID. Is there any way to do this thing in the report level. I tried it from the query level, but the result is not like what I wanted.

Please let me know if some body has any idea.

Thx.

Doing this in a report wouldn′t be the best way as you would get all the data from the server and then only would display a part of it. better filter the data on the server and send only back the appropiate results, then you would have no problem on the client / reporting service. Anway, if you want to do this, you might have a look at the RowNumber() property in Reporting Services. You could set the Visibility of the row to Visible=True if the RowNumber("GroupName") equals or is less than 3 =IIF(Rownumber("GroupName") <= 3;True;False)

Doing this on the server depends on which server version you are using. SQL Server 2005 probably would enable you to use ROW_NUMBER() on the server side. SQL Server 2k does not implement this new function, so you would have to use something else instead.
