Searching for Parts on Lot Number Entry

You could setup a quicksearch for the part.

Have a pull down list of the part classes that you would want to add.

Or retrieve all when you search and use the group by to select a specific part class.

On the Lot Number Entry screen there is a search button for part I would like to limit the number of parts by Part.ClassID, is this possible and if so how do is it done?
