Creating a Dynamic Matrix Based on Column Names in Every Table

[taylorb]

I have several reports using Roles to hide sensitive date. Each table with the sensitive data contains a column with the customer name called "CustomerSource" so only that customer should see the information in that row. I want a quick and easy way to validate the roles across several reports.

My ideal solution would be a hidden tab that has a matrix/table with a column for every table with a CustomerSource column and then it would list the distinct values in that column like this:

Table 1	Table 2	Table 3	Table 4	Table 5
Customer 1	Customer 1	Customer 1	Customer 1	Customer 1
Customer 2	Customer 2	Customer 2	Customer 2	Customer 2
Customer 3	Customer 3	Customer 3	Customer 3	Customer 3
Customer 4	Customer 4	Customer 4	Customer 4	Customer 4

Then when I view as a role (e.g. Customer1Role) if it was working it would only show Customer 1 in the table like this:

Table 1	Table 2	Table 3	Table 4	Table 5
Customer 1	Customer 1	Customer 1	Customer 1	Customer 1

Or if there was an issue it would show more values than intended:

Table 1	Table 2	Table 3	Table 4	Table 5
Customer 1	Customer 1	Customer 1	Customer 1	Customer 1
		Customer 2

The issue is that I want to be able to quickly build this visual out in multiple reports. Is there a way with DAX to check every table for a certain column name and then display those values?

Hi, @taylorb 

According to your description, I guess you want to get a table that displays the [CustomerSource] column in the five tables, and the value should be the user who views this report. I think you can not achieve this in a simple DAX, you can create measures for each table to get the expected result, you can take a look at my steps:

1. Create the five measures in five tables (one by one):

Table1 = CALCULATE(MAX('Table1'[CustomerSource]),FILTER('Table1',[CustomerSource]=USERPRINCIPALNAME()))

Table2 = CALCULATE(MAX('Table1'[CustomerSource]),FILTER('Table2',[CustomerSource]=USERPRINCIPALNAME()))

Table3 = CALCULATE(MAX('Table1'[CustomerSource]),FILTER('Table3',[CustomerSource]=USERPRINCIPALNAME()))

Table4 = CALCULATE(MAX('Table1'[CustomerSource]),FILTER('Table4',[CustomerSource]=USERPRINCIPALNAME()))

Table5 = CALCULATE(MAX('Table1'[CustomerSource]),FILTER('Table5',[CustomerSource]=USERPRINCIPALNAME()))

2. Create a table chart and place them into it, and view as a username, you can get what you want, like this:

If this result is not what you want, you can post some sample data(without sensitive data) and your expected result.
