Selected Value with lookups HELP

Hi gsed99 ,

According to your description, here are my steps you can follow as a solution.

(1) My test data is the same as yours.

(2) We can create a slicer table and a measure. 

Slicer = VALUES('Table'[Account ID])

Cohort = 
var _industry=CALCULATE(MAX('Table'[Industry]),FILTER(ALLSELECTED('Table'),[Account ID]=SELECTEDVALUE('Slicer'[Account ID])))
var _country=CALCULATE(MAX('Table'[Country]),FILTER(ALLSELECTED('Table'),[Account ID]=SELECTEDVALUE('Slicer'[Account ID])))
RETURN IF(MAX('Table'[Account ID])=SELECTEDVALUE('Slicer'[Account ID]),"1",IF(MAX('Table'[Industry])=_country,"2",IF(MAX('Table'[Country])=_country,"3","Other")))

(3) Then the result is as follows.

Best Regards,

Neeko Tang
