When a part pick list is selected from the list, the pick list items are shown on the right side. There is one row per each part. Row shows information of the part and the amount which is to be picked.
You can select Target Location to define the storage location where the part is picked to.
If stock item selection is used (NWSPickingUseStockItemSelection = Always), under the pick list items, there are the selection lists for the stock items. The Available items or Selected items can be viewed per one pick list item row at a time.
When pick list items are ready for picking, the whole pick list can be picked by clicking Pick All. You can also pick only specific pick list items by selecting the items, and clicking Pick Selected.
