Drill Down Matrix Report in SSRS
We are going to use the below-shown report to Enable the Drill-Down in SSRS Matrix Reports. Please refer Matrix Report, Data Source, and Dataset articles to understand the creation of Data Source, Dataset, and Matrix report.
If you observe the below screenshot, It was a normal Matrix report with Country, State Column as Row Group and Gender, Occupation as Column Group.

Add Totals to SSRS Matrix Report
Right-click on the Aggregated data column will open the context menu with multiple options. Please select the Add TotalOption and then choose Row or Column as per your requirement. Here we are selecting Row. It will generate new Row below the existing Row with Row Total

Next, we are selecting Column. It means It will create a new column on the right side to the existing row with Column Total

TIP: You can always change the default aggregate function SUM to other functions by selecting the fx Expression from the above screenshot.
We can add the Grand total by selecting the empty cell in between the Row Total and Column Total. Next, add the Sales Amount column to that cell.

We changed the Background Color of the Grand Total cell to show you the difference between Row, Column, and Grand Total. Click on the Preview tab to see the Report Preview
