I have a setup like this Client Partner (a client record with a one to many table) Income Plans

A client can have one partner A client can have many income plan A partner can have many income plans (because they are a client)

What we need to do is when viewing the client we need to display not only my income plans but also my partners income plans

I have it displaying the clients income plans, but I don't know how I can also get the partners income plans to display.

Is this possible?
