The problem is: how to group (merge) those 3 cells. Because this a matrix, the columns are generated by a dataset, so this should be related to something like "dynamic merging cells". I think this not about adding a row group or column group. You can see I have used row groups in the week row and month row.

I wonder if somebody has any idea how to support this. If not, is there any other alternatives, as long as they can produce this result.

I am using SQL Server Reporting Services 2000 SP2

Thank you VERY MUCH!

Nobody has any idea? Or I didn't put something clear?

I need helps.
