I have a sales order with several lines of the same sales category. Some of the line are negative, as the customer has done some prepayments, but the total of the sales order is positive for the sales category.
When I try to post the invoice for the SO, I get the error "Update quantity is greater than remaining/delivered quantity" - How is this possible for invoicing on sales categories?
The sales order type is Subscription. If I make the same lines from a "Sales order" order type, the problem does not exist!
Have someone experienced a similar error, or know what this error is based on?
