Paying off part of the yield, but not all of it and paying the unpaid part later

Hi,

I'm looking for a way to pay only part of the yield payment if you get negative cash in case you pay all, but if you pay nothing you have positive cash. The part that is then not paid I would like to have in the "Overdue" row, so I can see how much I am behind. I would like to pay off this Overdue account, but with the same conditions as the original payments, only pay off until ending cash is 0.

In the attachments you can find a situation where the ending cash is >0, but in the model I have now, this means that I don't pay anything, because I can't pay all.

Kind regards,

Matt
