New Colum based on ID

[Kat_00]

I'm looking to create a new column in my data model that displays different values based on the user[ID]:

1. If user[ID] >= 50, I want to retrieve the name from the entity table using the formula: LOOKUPVALUE(entity[Name], entity[Entity ID], user[Entity ID])

2. If user[ID] < 50, I want to retrieve the name from the old_entity table using the formula: LOOKUPVALUE(old_entity[Name], old_entity[Entity ID], user[Entity ID])

I'm not sure how to accomplish this in DAX. Can anyone help with the correct DAX formula for this scenario?

Thank you!

@Kat_00 Seems like:

Column in User Table =
  VAR __ID = [ID]
  VAR __Result = 
    SWITCH( TRUE(),
      [ID] >= 50, LOOKUPVALUE( entity[Name], entity[Entity ID], __ID ),
      LOOKUPVALUE( old_entity[Name], old_entity[Entity ID], __ID )
    )
RETURN
  __Result
