Packaging query

Question

How is packaging process(along with Handling Unit) is carried out and is linked to delivery

Answer 1

Packing for Inbound and Outbound Deliveries
Use
Packing delivery items is carried out right in the delivery itself. From the overview screen, choose Edit ® Pack in order to access the packing screen.
Features
The following functions are available during packing:
Packing delivery items in handling units (HUs) and allocating individual items to several handling units.
In addition to the standard packing of delivery items in handling units, you have the option of automatically packing a specific quantity into several different handling units.
Multi-level packing
You can pack handling units in one another. In this case, packing is multi-level. The number of possible packing levels is 999999.
Unpacking items that were already packed
Items that have already been packed can be unpacked again. This is also the case for handling units that were packed in multiple levels.
Responses to exceeding weight or volume
If the weight or volume limit is reached when packing items in handling units, then only the maximum packable partial quantity is packed. If you have selected another handling unit that has space for packing, the remaining quantities are packed into that handling unit.
Deleting handling units
Handling units can be deleted in the delivery. First, the handling unit that is to be deleted is unpacked and then it is removed from any higher-level handling units (if applicable) before it is actually deleted.
Emptying handling units
Handling units can be emptied out. Unlike unpacking, where only selected items are removed from the HU, here the handling unit in question is emptied completely.
Handling unit single entry
You can enter HUs and HU contents manually by using the single entry function.
Changing packing quantities
Changing the packing quantities is possible in various overviews. However, the packing quantities can no longer be changed after goods issue has been posted. In Customizing for packing, you can specify further conditions under which packing is not to be possible.
Creating delivery items from handling units
Delivery items can be created from handling units. In this way, it is possible to keep inventory for packaging materials and also to include packaging material in the invoice. To accomplish this, the system must generate delivery items for packaging materials, which must be set for the delivery type in Customizing, and the packaging material type must suggest delivery item generation as a default.
Displaying the Allowed packaging materials
You can display a list of all allowed packaging materials for an item to be packed, as long as the material group Packaging material is maintained in the packaging data in the material master for the material concerned.
Checking for allowed packaging materials
A check is carried out to make sure that the packaging material is intended for packing a certain material. Customizing for packing is used to control which packaging materials are allowed for packing.
Packing proposals in sales orders and scheduling agreements
It is possible to enter packing proposals in sales orders and scheduling agreements. These specifications automatically lead to a packing proposal in the delivery if a special data transfer routine is maintained in Customizing for copying control between the sales documents and the delivery. The packing proposal can be changed in the delivery. It is also possible to pack the delivery according to the packing proposal in the preceding document by using the Use proposal function in delivery processing.
Packing and decentralized Warehouse Management
If you are working with  decentralized Warehouse Management, packing takes place in several steps.
The packing proposal that was determined in the central system is reported to the decentralized system.
The packing proposal can be copied or changed in the decentralized system, depending on the actual packing process.
With confirmation of the delivery to the central system, the original packing proposal is deleted and is replaced by the actual packing from the decentralized system.
Automatic packing and batch split
For a batch split in the delivery, you can set the item category in Customizing to indicate whether the entire batch quantity or only an individual batch item is to be packed.
If you enter " " in the Pack batch main item field and no split items are available, then no items are proposed for packing. If the delivery item contains an HU-managed storage location, this delivery item must be packed at the split level. In this case, the indicator (pack batch main item) is overridden.
If a packing proposal has been defined in the order for materials that are handled in batches, and if automatic batch determination is not carried out when a delivery is created, then this delivery is not automatically packed.
You must then pack this delivery manually (see also Automatic packing in the delivery).
Example for packing with batch split, taking the Batch main item indicator into consideration:

Creating packing data from subsystems
It is possible to copy packaging data from subsystems to the delivery.
Cross-delivery packing in shipment processing
In shipment processing you can pack in the following ways:
Delivery items that have not been packed in the delivery and which are not required to be packed in the delivery can be packed.
Highest-level handling units in the delivery can be packed in shipment handling-units.
Since the packing depends on the shipment, different packing methods can be used in a follow-up shipment with the same deliveries. If a delivery HU is packed in a shipment HU, the entire contents of the handling unit in the delivery can no longer be changed. No storage units are created for shipment HUs.
The following diagram shows how handling units are packed in the delivery.
