Each Inventory Item can be categorised under one or more Model codes. These codes provide a quick way of searching and selecting Products on Jobs and Invoices. The list of available Models, and the Manufacturer for each is defined in Codes Setup. Use the top dropdown to filter the Available list to only show Models for the specific Manufacturer.

Select a module from the Available list and use the Right Arrow button to set it against the current Product. Use the Left Arrow button to remove the selected Model from this Product.
