Adding an OLAP Grid to an Existing Report
I want to add an aggregated OLAP grid view to an existing drill-down report.
You can quickly accomplish this by accessing the Insert OLAP Grid functionality from the main Insert menu. An alternative approach that might make sense in certain situations is to insert a subreport that points to the involved OLAP data source. Using a subreport to host the OLAP grid enables you to dynamically pass in parameters from the main report to the subreport and its associated OLAP grid. These parameters can dynamically filter the columns, rows, and slices of the involved OLAP grid(s).
