Self referencing tables

Hi Team

I've got a Table that references itself:

Referrer

-ContactID

-ParentContactID

-...

Patient

-PatientID

-ReferrerID(ContactID)

-...

The parent contact can be a department, an organisation or a team leader and can have multiple layers.

I'm trying to create a slicer or table that shows the individual referrer but also the organisation.

e.g.: Organisation A has Staff Member B and Staff Member C.

If I look at Organisation A I want to be able to see Staff Member B and Staff Member C's information and linked tables. Like the total amout of referrals for Organisation A.

I don't seem to be able to create a relationship between the two attributes of the same table. What would be the best way to achieve above task?

Thank you for your help

Daniel
