thank you, but I'm not sure this answers my question.  

we have our bank account linked to quickbooks.  I pulled in a deposit that was made to our bank account, lets say it was for 100K.  Usually, in the case of deposits, I can just "match" them to open invoices.  However, in this case, I want to match part of it and exclude part of it.

60K is for an open invoice

40K is the amount I want to exclude (this amount was reversed from our bank account a few days later, as a stop payment was put on the check by our client.)

how can I apply the 60K to an invoice and exclude the 40K from being mapped anywhere (it is going to be offset by a -40K and I just want them to cancel each other out.)

thanks.
