DAX dynamic RELATED function
I have a data table connected to multiple lookup tables, and I'm trying to find a way to use a the RELATED function to fetch values from a dynamically-selected lookup table based on the values of one of the columns.
e.g.
If the Month column's value is "2018_01", the Type column's value is "Adjustment", and the Variant column's value is "B", look in '2018_01_Adjustment'[Var_B] (essentially '<Month>_<Type>'[Var_<variant>]).
I was hoping DAX had some parallel to Excel's INDIRECT, but from looking through the internet, it appears it doesn't, so I need an alternative.

I found a workaround for part of the problem by combining some of the columns in each table into a reference key. The column references still require a SWITCH function. It's not as elegant a solution as I'd hoped for, but it does the job.

The most important thing using DAX is your data model.
For this type of question you need to model your data as thus:
First, do you have a date dimension? Once both the fact table (I think that's what you mean when you write "data table") have a link to the dimension table, you can link and group by the dimension you want, for example the MONTH or the YEAR.
