Hello Jelayca V,
Thanks.

But this is not what was bothering me.
I do not get what to connect with what and how.
This is situation 2, but the same problem.
We had made advanced payment to a hotel .
The total of final invoices was less because less nights spent there.
They paid us back more paid part of advance.

So, I have expense that is not closed for amount of 360.60 EUR (advance booked on A/P).
I create a credit note with the description as for other invoices related to that payment.
And then what?
How to close that credit note?
Whit what and how I close the expense?
Whit what I should connect transaction (payment back of 360.60 EUR) from the Bank feed?
