Topic: Invoice line needs negative qty

When selling goods like PC's I'd like to have an exchange on the same invoice. I was trying to put a negative quatity for the exchange PC on the invoice however FA doesn't seem to accept negative quantity nor negative price.

I would appreciate to understand how to deal with this.

Re: Invoice line needs negative qty

Is it possible to enter a negative quantity on the invoice?

It's not a real credit invoice which I need, I just like to sell a new PC and exchange the old one. This would be nice to see on the same invoice.

Re: Invoice line needs negative qty

Standard way of dealing with this situation  is just credit invoice issue. We could consider removing the constraint for item quantities being positive, but this could be done only as an option depending on related company setting. So maybe yes, but not in 2.2 final - it's too late for database changes.
