Back-to-Back Fulfillment in Oracle Inventory Cloud

Back-to-back fulfillment in Oracle Inventory Cloud is a supply chain process where supply is created only after a sales order is placed. This process links the demand (customer sales order) directly to the supply (procurement, manufacturing, transfer, or existing stock), ensuring efficient inventory management while meeting customer demands. Below is a detailed step-by-step explanation of the back-to-back fulfillment process.

1. Overview of Back-to-Back Fulfillment Process

The back-to-back (B2B) fulfillment process ensures that supply is created only when a customer order is received.

Supply is specifically reserved for the sales order until shipping.

This process helps reduce excess inventory while maintaining responsiveness to customer needs.

It supports four fulfillment strategies: Buy, Make, Transfer, and On Hand Reservation .

Back-to-back fulfillment is mainly used in discrete manufacturing environments.

2. Step-by-Step Back-to-Back Fulfillment Process in Oracle Inventory Cloud

The back-to-back fulfillment process consists of the following key steps:

Step 1: Process Sales Order

The sales order is created in Oracle Order Management .

The order is validated for correctness (items, quantities, prices, etc.).

The order is scheduled, and the system checks if on-hand inventory is available.

If no inventory is available, Oracle Supply Chain Orchestration initiates a back-to-back fulfillment request.

Step 2: Determine Supply Sources

Oracle Supply Chain Orchestration (SCO) determines the best supply source based on predefined rules and sourcing strategies.

The system evaluates the following supply options:

Buy : Procurement from an external supplier.

Make : Internal manufacturing or contract manufacturing.

Transfer : Movement of inventory from another warehouse or distribution center.

On Hand : Direct reservation of existing inventory.

Step 3: Create and Manage the Supply Order

A supply order is generated in Oracle Supply Chain Orchestration .

The order is assigned to the appropriate fulfillment method:

Buy Order : A purchase requisition is created in Oracle Procurement Cloud , and the supplier provides the required goods.

Make Order : A work order is created in Oracle Manufacturing Cloud , and production begins.

Transfer Order : A transfer request is initiated in Oracle Inventory Management , moving stock from another warehouse.

On-Hand Reservation : If stock is available, it is reserved against the sales order.

Oracle monitors the progress of the supply order until completion.

Step 4: Receive and Consolidate Supply in Warehouse

Once supply is procured, manufactured, or transferred, it is received in the fulfillment warehouse.

If it is a purchased item, a receipt is created in Oracle Receiving .

If it is a manufactured item, the work order is completed, and inventory is updated.

The system ensures that the received inventory is linked to the original sales order.

Step 5: Ship to Customer

The sales order is released for fulfillment.

A Pick Release process is initiated in Oracle Inventory Cloud to allocate stock.

The order is picked, packed, and shipped using Oracle Shipping Execution .

A shipping confirmation is generated, and an invoice is created in Oracle Receivables .

The sales order is marked as complete, and the supply order is closed.

3. Detailed Explanation of Back-to-Back Fulfillment Flows

1. Buy Flow (Procurement)

If the supply is sourced externally, the system generates a purchase order in Oracle Procurement Cloud.

The supplier delivers the goods, which are received in Oracle Receiving.

The inventory is updated, and the order is prepared for shipment.

The sales order is fulfilled once the goods arrive.

2. Make Flow (Manufacturing)

If the item is manufactured internally, a work order is created in Oracle Manufacturing Cloud.

Production is executed, and the finished product is stored in inventory.

The system reserves the item against the sales order.

The order is fulfilled when the product is available.

3. Transfer Flow (Warehouse Transfer)

If the item is available in another warehouse, a transfer order is generated in Oracle Inventory Cloud.

The inventory is moved to the fulfillment warehouse.

Once received, the inventory is reserved and prepared for shipment.

The sales order is completed upon shipment.

4. On Hand Flow (Inventory Reservation)

If the item is available in stock, the system directly reserves it.

The order moves to the shipping phase without additional procurement or manufacturing steps.

The pick, pack, and ship process is executed, and the order is fulfilled.

4. Key Benefits of Back-to-Back Fulfillment in Oracle Inventory Cloud

✔ Reduced Inventory Holding Costs – Stock is only procured, manufactured, or transferred when needed.

✔ Improved Order Fulfillment Efficiency – Orders are linked directly to supply, reducing delays.

✔ Better Customer Satisfaction – Customers receive products faster with reduced stockouts.

✔ Automated Supply Chain Coordination – Oracle Cloud applications ensure seamless integration between order management, procurement, manufacturing, and inventory.

The shipping process is initiated, and the order is delivered to the customer.

The sales order and supply order are closed.

Back-to-Back Fulfillment: Detailed Simulation in Oracle Cloud

Introduction

Back-to-back (B2B) fulfillment is a process where supply is created only after a sales order is placed. The supply is specifically reserved for that order and remains linked until fulfillment is completed. Unlike regular inventory processes, back-to-back fulfillment ensures that supply is directly tied to a customer demand, optimizing inventory management while maintaining customer satisfaction.

Key Oracle Fusion Cloud Applications Involved

Back-to-back fulfillment integrates multiple Oracle Fusion Cloud applications, including:

Oracle Order Management (for sales order processing)

Oracle Procurement (for external supply sourcing)

Oracle Manufacturing (for in-house production)

Oracle Inventory Management (for warehouse operations and fulfillment)

Oracle Supply Chain Orchestration (for coordinating supply processes)

Oracle Shipping Execution (for shipping to customers)

Step-by-Step Back-to-Back Fulfillment Simulation

Step 1: Creation of a Customer Sales Order (Source of Demand)

A customer places an order for a product that is not available in stock.

The sales order is created in Oracle Order Management .

The system checks inventory availability in Oracle Inventory Cloud .

Since stock is unavailable, the Supply Chain Orchestration (SCO) module triggers a supply request.

The system determines the best supply source based on sourcing rules (Buy, Make, Transfer, or On-Hand Reservation).

The sales order line is marked for back-to-back fulfillment, and a supply order is generated.

✅ System Action: The system reserves the sales order and waits for supply to be created.

Step 2: Creation and Fulfillment of Supply (Source of Supply to Warehouse)

Once the supply order is created, the system initiates one of the following supply methods:

Option 1: Buy (Procurement from Supplier)

The system generates a Purchase Requisition in Oracle Procurement Cloud .

The requisition is converted into a Purchase Order (PO) and sent to an external supplier.

The supplier fulfills the order and ships the goods to the fulfillment warehouse .

The warehouse receives the items using Oracle Receiving .

Option 2: Make (Manufacturing in-house or contract manufacturing)

The system generates a Work Order in Oracle Manufacturing Cloud .
