How to retrieve the role of a user from another table

[VincentA]

Hi,

I have two tables, one containing all users with their properties, including their roles.

The other table is used to record a type of operation done for a user, which has its own properties including the ID of the user who did it.

Both tables are related through the user ID.

For a report, I need to display :

User ID - Operator ID - Operator role

For the user ID, I use user.id. For operator ID, I use operation.operatorId. Then if I try to use user.role, it displays the role of the user while I want to display the role of the operator.

I figured I should add a new column in table operation which would reference the table user and the field role, and that it would display the role of the operator. But I have no idea of how to do that. Can someone help?

Thanks

@VincentA , You can got from 1 to many side

new column = related(Table2[role])

Many to one

New column = maxx(realtedtable(Table1), Table1[role])

Sorry, I don't understand what you mean by "one to many"/"many to one"?

I tried using the "RELATED" function since I read it in many posts but none of the examples work, it seems to only accept Power Query functions

Oh, I get it now from your videos. How to use that with a table name that has spaces?"

[VincentA]

I'm not getting it, I used the MAXX(RELATEDTABLE part but it always gives the same value. I want the value of the column to be relative to the user ID

It worked with the LOOKUPVALUE function! Thank you for your videos!

What I did :

Column= LOOKUPVALUE(user[role], user[id], operation[operatorId])

Hi @VincentA 

Could you share the headers of both tables, that would make it easier to suggest a solution

Yes, here it is for user table
id | name | email | etc | role

And for the operation table

id | status | protocol | operatorId | userId

userId = the ID of the user for who the operation was done

operatorId = the ID of the user who did the operation

Both ID are related in the source DB to the user table

Hi @VincentA 

You can also acheive your result in Power Query by merging both tables using the column id
