How to deal with many to many dimensions in Tabular?

[Anonymous]

I have this model:

Emp Roles is an unpivot that has Manager1 and Manager2 from Contracts and Manager1 and Manager2 from Clients:

• Each Contract/Client can appear multiple times in Fact.
• Each Fact row belongs to only one Contract and only one Client

As expected, a given client can have different contracts… (And, a given contract can belong to multiple clients too).

Therefore clients and contracts is Many to Many too.

My problem is that when in Power BI I combine a manager from Emp Roles with a fact measure I get some wrong results.

Is there any way for this to work?

Hi @Anonymous ,

You seem to be related two fact tables using a many-to-many relationship, please refer to:

Relate many-to-many facts

A good model is half the battle, and Power BI prefers to use a star schema  when modeling.
