LookUp Measure with Multiple Columns

Hello Power BI Gurus, 

Can you please help me with DAX for "Needed" Column?

I need to find a corresponding record for "Opposite Enity" and "Opposite Entry Type" combination  against "Entity"  and "Entry Type"  combination and  get amount from "Amount Column" .

Amount is a simple measure - it takes amount from "Amount USD" Table native Column and filters against calendar table (time intelligence year slicer)

"Opposite Entity" and "Opposite Entity Type" are Table columns

Individual values for Entity, Opposite Entity, Entry Types and Opposite Entry Types  repeat, however "Entity /Entry Type/ Opposite Entity/ Opposite Entry Type"  combinations are unique.


I tried merging the table to itself to handle this without DAX, but the table has many columns and it needs to be merged by multiple fields, I was not able to figure out how to do this without duplicating rows.

Hey @ogend ,


You can create a new custom column by concatenating multiple columns(the combination of which is unique). This custom column will act as a key in merging the table with itself and then you can extract the desired amount column.
