Dear all,
 
I have created a sales order with prepayment. The prepayment has been posted, paid and sales order has been released and delivered. Then i would like to post the invoice, but then i got the following message:

"Quantity must not be less than 0 in Sales Line" 
 
Could you please help me, thanks a lot.

    Hello,
     
    How did you deliver the order? Did you "Ship" only or "Ship&Invoice" ? Main invoice should already being posted if "Ship&Invoice" selected as posting option. If only shipped, you can crate a new sales invoice and use "get shipment lines function".

     Thanks for the reply. I did only "ship" and then when I try to invoice, the error message comes up

    you need to check the qty to invoice field on your sales order. It is possible this sales order has been shipped and invoiced by someone.
    You could take a look at the invoices from the sales order if this is the case. If not, you could fill out the qty on that field and post.

    What value do you have in the Quantity field?

    It looks like there might be a customization issue.

    Hope this can give you some hints.
