Fusion SCM – Implementing Back to Back Make Flow

by

Overview:

Sales Order demand triggers supply creation, and a hard link is established between the Sales Order and Supply Work Order. Back-Back fulfillment is used when we prefer not to keep stock on-hand and it is supported for Discrete Manufacturing only. Back to Back fulfillment is a 3 step process.

  1. Creation of Sales Order
  2. Creation of Supply Order – Purchase Requisition, Work Order or Transfer Order
  3. Shipment of Sales Order

Implementation Steps:

Below are the detailed steps to implement Back to Back Make Flow.

  1. Item Definition

Navigation: PIM > Tasks > Manage Items > Query for Item > Specifications (Tab) > Sales and Order Management (Sub-Tab)

Set the below item attributes

  • Check ATP = Material Only
  • ATP Components = Material Only
  • Back to Back enabled = Yes

Planning (Sub-Tab):

  • Make or Buy = Make

Manufacturing (Sub-Tab):

  • Build in WIP = Yes
  1. Item Structure (Bill of Material)

Navigation: PIM > Tasks > Manage Items > Query for Item > Structures (Tab) > Create

OR

PIM > Tasks > Create Item Structure

  • Make sure that the item structure (Bill of Material) is defined for the Back 2 Back Make Item. Some companies define the item structures (Bill of Materials) in their engineering systems and feed into the Oracle Fusion PIM.
  1. Work Definition (Routing)

    Navigation: Supply Chain Execution > Work Definition > Manage Work Definitions > Add (Creating Work Definitions)

    • Make sure that the Work Definition is defined for the Back 2 Back Make Item
    1. Sourcing Rule and Sourcing Assignment

    Define sourcing rule as Make, Then do the assignment at the Category & Org level OR Item & Org level to the GOP Assignment Set

    • Defining Make Sourcing Rule

    Navigation: Global Order Promising > Tasks > Manage Sourcing rules

    • GOP Assignment Set – Sourcing Assignment for Back2Back Item
    1. ATP Rule

    Navigation: Global Order Promising > Tasks > Manage ATP Rules > Create ATP Rule

    Note: Back to back functionality works, If Promising mode is supply Chain Availability search only. It won’t work for the ATP Rules based on Lead Time Based/Infinite Availability Based.

    1. Order Management parameters – Specify a procurer/preparer
      • Navigation: Setup & Maintenance > Manage Order Management Parameters

    This setup is required for Drop Ship and Back-to-Back Flows.

    7. Schedule “Release Planning Recommendations” ESS Job in frequent internals.

    The job releases supply recommendations from Global Order Promising to Supply Chain Orchestration to create Supply Order(s) (Work Orders/Purchase Requisitions/Transfer Orders).
