How to add a conditional column based on a column that is in another table?

Hi,

 

I need to add a new conditional column in my database, but this condition is related to a column that is in another table.

 

If the data in my column is not in the column in the other table, I need to bring me "1" else "0". But I can't create this condition.

 

For example:

vmzandonadi_0-1601068106648.png

Table 1

 

vmzandonadi_1-1601068203094.png

Table 2

 

If the value of my column "Group" is in the column "Code", return true (1) if not false (0).

 

How can I do this?

Hi, @Anonymous , you may try it this way,

= Table.AddColumn(#"Previous Step", each if List.Contains(#"Table 2"[Code], _) then 1 else 0)

Thanks to the great efforts by MS engineers to simplify syntax of DAX! Most beginners are SUCCESSFULLY MISLED to think that they could easily master DAX; but it turns out that the intricacy of the most frequently used RANKX() is still way beyond their comprehension!

DAX is simple, but NOT EASY!

@Anonymous If the tables are related, you can use RELATED or RELATEDTABLE. Otherwise you can use LOOKUPVALUE or MAXX(FILTER(...),...)
