1. Check in Shipping Transaction Form, make sure the order still in “Ready to Release”.

B) Do not have enough qty
C) Lot expired
D) Wrong reservation (even inventory have enough qty)
E) Inventory reserved for other orders.
F) Inventory picked up by other orders
G) Previously return to stock not done properly.
3. Case A,
Check if the order is on hold. Check the order type in Shipping Transaction Form → “Detail” →“Source”.
4. There is another way to check the order type. That is go to WMS Control Board → “Picking”.
5. Or go to OM Shipping View to see the order type.
6. Go to the correct “Sales Order View” instant accordingly by keying in the order# and order type.
7. Click on “Open Order” → “Action” → “Additional order info”.
8. Do the same for order level and line level.
9. Case B & C,
-Go to Material Workbench to check if the lot has expired or not having enough inventory for this order.
10. We can check if any lot is reserved for other order as well.
11. In Material Work Bench, go check for each lot in the physical locator by clicking on the “Attribute” button. (lot level reservation)
12. Alternatively, go to Shipping Transaction Form → OM Shipping View,
-or go to “Lot Number” (Ctrl + L), click on Attribute column to check the SO reservation of the lot.
13. Compare the SO info with the order that are having problem.
14. Case D,
-Go “Reserve Supply” form (Ctrl + L) to check if the order is wrongly reserved.
15. Case E,
-in the “Reserve Supply form, we can check if the qty is being picked up by other order as well. (order level reservation regardless of lot)
16. Also, can go to Material Workbench → Availability, to check for the available to reserve.
17. Case F,
-it might have high possibility the qty is taken up by order with different line, or other orders which have been auto launched.
18. If this is the case, must do backorder.
19. Go to Transact Move Order Form → tab “Pick Wave” → View/Update allocation → Lot/Serial.
20. Click on the checkbox for order which need to be backordered, then go to Tool → Back Order Line.

23. Check the lot state, must be in “Resides in inventory”.
24. Check in Material Workbench to see if the lot is still packed with LPN or not.
25. Check also if the lot is in physical locator rather than logical locator.
1 Back Orders

  • The Oracle “term” backorder is astatus on the order line or delivery line indicating that you have tried to release an order for picking in your warehouse, but that the pick release was UNSUCCESSFUL because there was no available inventory.(Backorder can be partial or complete). The Oracle term backorder does NOT mean that you have open purchase orders for the out-of-stock item from your vendors.
  • The term  backorder is also used in business a little differently than in Oracle. The term “An item is on backorder” usually means that the item is not in stock, but the shipping company has already placed purchase orders from their suppliers to restock the item.
  • Backorder is when you do not fulfill the Sales Order, or if the inventory is out of stock for delivery to customer.

2 Drop Shipment

  • Drop shipment on the other hand is a method of order fulfillment where the organization taking the order does NOT maintain their own inventory for the drop-shipped product, but fulfill their orders through 3rd party vendors who directly ship to the end customer ordering the product.

For example,

  • A orders item x from B
  • B orders item x from C
  • C ships Item x to A.
  • B bills A for the order, C bills B for the order

A – Customer
B – Oracle Processing Company
C – Supplier

3 Back to Back Orders

In Back to Back Order the shipment process is also completed through OM as a standard order after the item is received against a PO.

What is the major difference between drop shipment and back to back order ?

  • In B2B the source will be internal but the item would be procured after the order is created or after the demand is made.
  • In Drop Ship the source will be external
  • In Drop Ship orders, material is directly shipped to the customer from the supplier. Thus, inventory is not affected. In this case, only logical receiving is done. But in the case of Back-to-Back orders, material is taken from inventory.
  • Drop Ship orders may have many Purchase Orders connected to them. In Back-to-Back orders one PO is tied to one Sales Order.
More on Drop Shipment & Back to Back Orders(Functional)
High Points for EBS Base Functionality for Drop Shipment
  • Drop shipment order processing in EBS is managed using workflow
  • Drop ship functionality is based on source type of an order line (Internal/External)
  • You can automate your PO/BPA release creation based on ASL/sourcing rule information
  • Drop ship process uses standard OM workflows.
  • You can use Sales order Purchase order discrepancy report to identify discrepancies between the OM and the PO
  • There is a links OM and PO to provide visibility through entire supply chain Flow.
The entire Drop shipment process flow can be best understood as figure below: 
drop shipment
Points for Implementation Considerations
  • Order line attribute: Source Type (need to be external). You can be defaulted from item or order type
    • Menu -> Responsibility Order Entry Super User/setup/Orders/Types
    • Setup an order type using the cycle defined in the previous step (a),an order number source, a valid standard value rule set.
  • Item attributes (OM and Purchasing)

You need to do the setup for these attributes:

-Purchased (PO) Enabled
-Purchasable (PO) Enabled
-Transactable (INV) Enabled
-Stockable (INV) Optional
-Reservable (INV) Optional
-Inventory Item (INV) Optional
-Customer Ordered (OE) Enabled
-Customer Orders Enabled (OE) Enabled
-Internal Ordered (OE) Disabled
-Internal Orders Enabled (OE) Disabled
-Shippable (OE) Optional
-OE Transactable (OE) Enabled

  • Setup requisition import parameters
  • You can also use grouping by Vendor
  • You can also set the multiple distributions set to No
  • ASL and/or Sourcing rule relationship need to be setup for Automatic PO creation
  • Oracle recommends using a logical organization for drop shipment. Exclude this organization for planning purposes. It can be worked around using non nettable Dropship subinventory

 Back to Back Order
As mention above this is ability to create specific supply orders for customer sales orders.
These are main features avaible in EBS

  • Designate specific items as B2B orderable
  • Enter sales order lines for these items, and have the supply automatically created via a requisition
  • Have the requisition converted into a Purchase Order or a release of a blanket Purchase Order
  • View the requisition number or PO number and its status from the Sales Order (using reservation details window)
  • Reserve the supply from the Requisition to the PO and finally to the Sales Order once the PO is received
  • Pick, ship and finally invoice the customer for the product.
  • Note to Buyer’s field in the requisition captures the Sales order information
  • Line status information shows the progress of the order
    PO Req Created
    PO Req Requested
    PO Created
    PO Received
  • If line is manually reserved it progresses to “Awaiting Shipping”
  • Changes and Cancellations on sales orders:
    • Reservation is changed
    • Notification sent to Buyer
