How to add Dynamic SQL Pivot tables to SSRS tablix

Hi Guys,

I have a SQL query that uses dynamic columns using SQL Pivot. I need to add this to a Tablix in a SSRS report as a dataset.

I have add this as a SP to the dataset. But when I try to run the SP in dataset mode none of the columns are displayed.

Can I do this using a SP? I cannot use a Matrix cause my objective is to get interactive sorting enabled. On Matrix interactive sorting is not supported on dynamic column groups.

Any help guys?

Thanks
