Show different sub-headings under each heading of a matrix

[amyvgordon]

Hi All, 

I am creating a dashboard for a retail business that has multiple outlets. Each outlet has a set of KPI's that are slightly different. Is there a way I can show different sub-headings under each heading on a matrix. 

By way of example, our existing report (in excel) is set up with headers like this (with all headers merged) :

Heading:	Visitors		Outlet 1			Outlet 2
Sub-Heading:	Site 1	Site 2	Transactions	Sales	COGS	Average Transaction Value	Transactions	Sales	COGS

I could easily do this by creating a different measure for each column, but given the number of outlets is likely to grow I'm reluctant to do this as it creates a lot of work to update the reports every time the structure of the business changes. 

I've already got a data source with the planned structure outlined, but it's displaying the correct values where I come unstuck. Is there a way I could set this up to dynamically change the measure shown according to the column headings?

Thanks!

Hi @amyvgordon ,

Isn't your data structure like this:

If it is, simply put the Heading and Sub-Heading columns in a matrix Columns, Value in matrix Values. In this way, although you add rows in the data source, the visual can still get correct result.

Hi @v-yanjiang-msft ,

My data is much more complicated than that unfortunately. There are four tables that drive the values I want to show in my matrix, and some of the matrix columns use data from more than one of the tables. 

I could group the data in to a table in a query or a dax table I suppose, but that's going to increase processing time significantly because of how much data I'm working with. 

Thanks,
