Revising an MBOM Using a Markup

Revising an MBOM is a series of tasks that involves different objects that follow their respective lifecycles and can include different users. The process can vary depending on your specific system configuration. This procedure summarizes a common way to revise an MBOM.

Before you begin:
  • Identify an end item part in the Released state that you want to modify.
  • Familiarize yourself with the different types change orders and markups and their effect upon MBOMs. See About BOM Markups.
  1. A Manufacturing Engineer or Senior Manufacturing Engineer creates a change order (CO) for affected items.
    The CO starts in the Create state, and then progresses through its lifecycle.

    and/or

    A Senior Design Engineer or Senior Manufacturing Engineer creates a Manufacturing Engineering Change Order (MECO) for affected items. See Creating an MECO.

    The MECO starts in the Create state, and then progresses through its lifecycle. See MECO Lifecycle.

  2. Open the part’s MBOM from the EBOM Common tab. See Part Bill of Materials - Plant Preferences View.
  3. From the Plant Preferences tab, a Manufacturing Engineer or Senior Manufacturing Engineer creates an EBOM markup or a plant BOM markup (for plant attribute changes only). See Creating a BOM Markup.

    The markup starts in the Proposed state, and then progresses through its lifecycle. See BOM Item Markup Lifecycle.

  4. From the CA’s or MECO’s Affected Items page, the owner promotes the markup to the Approved state. See Proposed Changes Page.
    The markup enters the Approved state.
  5. The CA or MECO owner applies the markup. See Applying a BOM Markup.
    The markup enters the Applied state.
  6. From the CA’s or MECO’s Lifecycle page, the owner promotes the CA or MECO. See Promoting an Item.
    Note: If using both EBOM and Plant BOM markups, release the MECO before the CA.

The MECO progresses through the Create and Review states. When it reaches the Release state, all BOMs corresponding to the changes released by the MECO are activated for the affected plants.

The CA progresses through the Define Components and Design Work states. After final approval in the Review state, the system automatically generates a new MBOM and the Responsible Manufacturing Engineer of the associated change object is notified.
