Re: Dax question about comparing non-adjacent row values in same column

Hey,
wondering if you considered to use
LOOKUPVALUE 

https://msdn.microsoft.com/en-us/query-bi/dax/lookupvalue-function-dax

in combination with unpivoting the columns TestItem1 ... TestItem3

 

 

If this is not what you are looking for, please consider to create a pbix file that contains sample data, upload the file to onedrive or dropbox and share the link.

Re: Dax question about comparing non-adjacent row values in same column

Looks like that could work. Could it be done without hard coding all the search column values?

Hey,

 

basically you can use variables that reduces hardcoding dramtically, also consider to pivot the columns Testresult1 - Testresult3 into one column

 

Everything gets much more simple if you provid a pbix with sample data, upload the file to onedrive or dropbox and share the link.
