Power BI Builder Matrix Grouping

Hi amsrivastavaa ,

Use the matrix wizard to provide a starting design on which to display data. The preview pane in the wizard helps you to visualize the result of grouping data before you complete the matrix design.

1. On the Arrange fields page, drag Territory from Available fields to Row groups.
2. Drag SalesDate to Row groups and place it below Territory.
3. The order in which fields are listed in Row groups defines the group hierarchy. Steps 1 and 2 organize the values of the fields first by territory, and then by sales date.
4. Drag Subcategory to Column groups.
5. Drag Product to Column groups and place it below Subcategory
6. Drag Sales to Values. 
7. Drag Quantity to Values.
8. Click Next.
9. On the Choose the Layout page, under Options, verify that Show subtotals and grand totals is selected.
10. Verify that Blocked, subtotal below is selected.
11. Verify the option Expand/collapse groups is selected.
12. Click Next.
13. Click Finish.
14. Click Run to preview the report.
15. Expand a subcategory. You can see the report quickly gets quite wide.
