Many to Many between 2 tables in Tabular

I have a simple Tabular solution where I want to enable reporting on 2 tables which are like

Table A: ID, SubID, Name, Qnty, Price

Table B: ID, ExceptionMsg

These are related in many-2-many since there can be multiple entries for 1 ID in Table A and 1 ID can have multiple ExceptionMsgs. I want to establish relationship between these 2 to enable users to look at all exceptionMsgs for a given ID. But Tabular doesnt allow to set up a relationship since Tabular doesnt support Many-2-Many. 

I found an article by Marco Russo which talks about using DAX for M2M for aggregating measures, but in my case I dont want to do reporting on measures for many to many, just attributes. Is there any way I can do many to many for my reporting?
