Hello

in our factory customer sends us a request for quotation for a specific product or group of products in certain quantities and sometimes the production capacity of the factory is not enough, or all the required quantities or we may send quotations with all the required quantities but when the customer sends us a purchase order sometimes it may be In less quantities than we sent in the quotation or all items may not be requested . for some tracking i've created additional 2 coulms for quantity and for the proucts that haven't ordered by customer i put quantity zero and i hide order lines when quantity is equal zero . this is working well while printing but when sending quotation by mail and the customer sign to quotation these lines appear. how can i hide them when customer sign quotation or in other word i want customer to see a replica of the attached or printed report how can i do this?
