In this menu option you control for each category whether it can be packed or whether it requires packing. If an item category is characterized as requiring packing, the item must be packed in delivery, before goods issue. If it can be packed, you can pack it. You cannot pack items with an item category which cannot be packed.
For materials to be handled in batches, you control whether only items with batch available can be packed, or basically the cumulated main item quantity is packed.
For each item category, enter either the packing control "A" for item
categories requiring packing or "B" for item categories which cannot be packed or, leave the field empty if you want to characterize the item category as "can be packed".
