How to see IDR detailed configuration?

Summary:

Hello is there anywhere where we can see the detailed configuration of IDR or what it's learnt and what attributes it is looking for on a invoice document?

We have issues where for example, our business is made up of 10+ companies each of those is created as it's own B/U and legal entity, but sometimes when an invoice comes through it selects the correct B/U but a wildly different legal entity. It would be good to know how it's deciding what it selects.
