In DAX I can use RELATEDTABLE to get a table of data I want to refine.
I can use FILTER to reduce the table to 1 row that contains the data I actually want.
I can use COUNTROWS to verify that I have 1 row like this:
TEST = COUNTROWS(FILTER(RELATEDTABLE(Config), AND([ConfigColumn1]=="Value1", [ConfigColumn2]==[LocalColumn]))), but how do I actually access the value in a specific column?
How do I get the value of ConfigColumn3 of the first, and only row?
