When using 'Copy Lines' on a quote, once you input the target quote to get the lines from we check the current parent company's Product Authorisation against the restrictions of the products on the target quote. If the current parent company does not have the same Authorisations used on the target quote, you get a warning 'This action cannot be performed because of the product restrictions for this Company', and prevents you from copying any lines.
It would be beneficial if we still allowed for the lines to be selected, but greyed out the lines that have the restrictions that are not applied to the parent company. This would at least allow the user to copy the lines that have no restrictions applied to them.
