On Sales Quotation Line, I created a custom reference field called Product Structure that will display the Product Structure Revision No and Alternate No. The user is required to choose the correct Product Structure for the shop order as a means of communication to the order processing team.
Right now, the LOV shows all product structures for all parts and the user has to manually filter the list based on the sales part. I want the LOV to default the Part_No filter to the Sales Part (CatalonNo) chosen on the OrderQuotationLine. I cannot find a good walkthrough online. Can anyone assist?
