Hi....I want to filter the list of items when looking up in the No. field on the sales order line. Specifically, I want to only show items with a certain BRAND (Global Dimension 1), where the 'Allowed Brands' are configured against the customer. So if I have 10 brands, A to J, and customer X is allowed to buy items with brands B, E and H, on looking up on the No. field from the sales line, only items that have brands B, E and H are listed. This means I need a table/page linked to the customer to record that customer X can only buy items with brands B, E and H. I think this will almost certainly need custom code, but wondered if anyone had any ideas on how to achieve this?
