I'm struggeling with my relations.
Let brake it down first.
I have an ingoing and and outgoing tabel.
They have to be connected to either paypal or the bank table.
See the image for my goal.
But I can't seem to be able to connect them. Although I can't exactly wrap my head around it, I can imagine creating shuch a relation creates a loop. I can only create 3 out of 4 releations.
