[GNC] How to suppress automatic refund fill-in for overpayment

Hi Tim,

I had sent this before but my mail was blocked by your hosting provider. I'll now resend to list 
only, perhaps this will reach you. To all others, sorry for the double post.

Hi Tim,

Just to be sure I understand correctly what's happening:

So you have at some point used the Process Payment window to enter a 
prepayment for a customer.
That at some point later you write the first invoice for that customer.
As the customer has already paid in advance you'd now like to link part of the 
prepayment to that invoice.
If you use the process payment window to do so (by selecting both the 
prepayment and the invoice) it will fill the Refund field.

When doing this manually it will always fill that field indeed. The only way I 
have  found to avoid this is to configure gnucash to automatically pay 
invoices on posting. You can enable this via
Edit->Preferences->Business->(Invoices)Process Payments on Posting

Regards,

Geert
