Calculated column. 3 different tables IF/ CASE statement

[Anonymous]

Hello, 

I am trying to create a calculated column between 3 different tables. All 3 tables are connected on a filed called 'ITEMID' field.

Does someone know how to write it correctly please?

IF 'Staging'[CODE]='ITEM_DIVERT'[CODE] AND 'Staging'[CODE]='KILLS_DISPOSITION'[CODE] THEN 'Match between 3 tables'
IF 'Staging'[CODE]='ITEM_DIVERT'[CODE] AND 'Staging'[CODE] != 'KILLS_DISPOSITION'[CODE] THEN 'Match between Staging & Item_Divert'
IF 'Staging'[CODE]!='ITEM_DIVERT'[CODE] AND 'Staging'[CODE] = 'KILLS_DISPOSITION'[CODE] THEN 'Match between Staging & Divert_Code'
IF 'Staging'[CODE]!='ITEM_DIVERT'[CODE] AND 'Staging'[CODE] != 'KILLS_DISPOSITION'[CODE] THEN 'No match'
END AS 'Comparison'

@Anonymous , You have bring other column this table using one of the 4 ways. You can bring them in var of the column

refer 4 ways (related, relatedtable, lookupvalue, sumx/minx/maxx with filter) to copy data from one table to another

The syntax of if in power bi Dax id 

If(<Condition>, <Then>, <else>)

You can use switch
