In order to associate a part line from a Purchase Order with a Sales Order, that particular part requires a Sales Order to be raised for it in the system. If there is no Sales Order raised for that particular part, then the system will not display the option to Associate With Sales Order.
Unable to associate a part on a Purchase Order with a Sales Order
When raising parts on a Purchase order there are instances when we want to associate this with a Sales Order, however the option is not always available.
