The item category (set in Customizing) controls the business scenarios that you can carry out with your allocation table.
Direct Delivery from Vendor to Recipient
The merchandise is ordered from a vendor and delivered direct to the recipients. In this case, the merchandise does not go through the distribution center. The only follow-on documents generated are vendor purchase orders.
Delivery from Vendor to Distribution Center and then to Recipient
Two movements of merchandise are involved:
The merchandise is ordered from a vendor and delivered to one or more distribution centers. Vendor purchase orders are generated as follow-on documents for this.
Once the vendor has delivered the goods to the distribution center, it is then sent to the recipients. Warehouse orders or deliveries are generated as follow-on documents for this.
A warehouse order is best used when the goods movement is to be planned, monitored or even billed. Warehouse orders can also be included in the requirements planning run in the receiving site. The purchasing functions that can be used when a warehouse order is placed are determined by the order type (standard purchase order or stock transfer).
If all the data relevant to shipping has already been maintained in the allocation table, only a delivery can be generated for the movement of goods from a distribution center to a site. Only in this case is a line item created in the delivery due list.
You can make changes to a delivery that has already been generated if the shipping situation changes or if you wish to confirm the quantity actually picked. You can also display the deliveries if you wish to see the shipping information.
Delivery (Out of Warehouse Stock) from Distribution Center to Recipient
In this case, existing stock on-hand is allocated among the recipients. The distribution center does therefore not need to order anything from a vendor. Warehouse orders or deliveries are generated as follow-on documents for this.
