PBI Report Matrix formatting - Values in Grand Total only


I have a report requirement and I am using PBI to visualize. The layout required is very similar to the Matrix visual. I am trying to report on Measure (SCADA Volume) by date on the columns. I want some additional measures to print ONLY FOR THE GRAND TOTAL, after all of the dates.

When I add these Measures to the Matrix Values, the measures are printed for every date. How can I apply formatting that will show those Measures only in the Grand Totals?

Solution Update

The "asymetrical columns" solution recommended (by David) was the answer. The solution is to create a Calculation Group with defined calculation for each individual column needed in the matrix.

My case required dynamic reference to trailing dates; That also required some calc columns on the 'Calendar' table to find the correct dates.

Solution

  • You need to create what's known as an asymmetric matrix. It is quite an involved process and requires the use of a disconnected table. It is probably a bit much to describe the whole technique here so instead you can follow the guide on this link: https://exceleratorbi.com.au/building-a-matrix-with-asymmetrical-columns-and-rows-in-power-bi/
