How to link the multi level marketing with 2 columns only?

Let’s say the customer A has the direct link with customer B because it has the referral id, some goes to customer C, customer B also has link with customer C.

My question is how I get to know Customer A has the link with Customer C and infinity link till it can count Customer Z also has link with Customer A?:wink: thanks

anyone could help me on this?

There’s no good easy way to do this with AppSheet.

which mean it is quite impossible to create a multi level marketing system here right?:blush:
