OK, it's ready. Enjoy! Let me know what you think.

Dear Mr Rost,
Thank you for your very instructive videos on ordering-invoicing. I have a question. In our company's ordering-invoicing process, first we have to issue a quotation document, citing only the products description, without prices, and then we issue a pro-forma invoice (let's say it is the order/invoicing document), with both the product description and the prices. How can I manage to issue the quotation document, without having the products added up to the orderdetailq list? That is, In such a routine, we select the products twice (once without prices and another one with prices), thus they are added up to the order lists twice. I would very much appreciate your suggestions upon this matter. Best Regards and thank you in advance.

Why don't you just create a separate report that doesn't have prices?

Dear Mr Rost,
Thank you very much for your reply. However, in our business, not all quotations may result in actual orders/invoices. Thus, if we issue a quotation (offer), the products add up to the orderdetailq with, or, without prices. Is there a way, when the quotation doesn't ends to actual order/invoice, for the products to be removed from the orderdetailq, since, we do not want them to automatically add up to it. In this way, we may use the orderdetailq to estimate the total sales in volume and price per product (as it will include only the quotations that converted to sales). Could we also achieve this by using some kind of criteria on the orderdetailq list? Thank you very much in advance.

In that case, just create the quote, copy it, adjust it, and then issue the invoice from the copy.

Thank you very much for your response!
