When a pick list is selected, the pick list items are shown on the right side. There is one row per each pick list item. The row shows information about the material and the amount which is to be picked.
Depending on your configuration, you can select materials from the stock for the pick list, or the software automatically selects or creates temporary dummy materials. If picking is configured to be mandatory, the work does not display in the Workshop Cutting until you pick the material.
