Create an MCN based on an ECN

Resolving changes to a complex bill of materials (BOM) or bill of process (BOP) can be a time-consuming process. You can use a manufacturing change notice (MCN) to make it easier to track an engineering change notice (ECN).

Procedure

  1. Open the work package that contains the ECN and on the Manage Work Package page, click Changes .

  2. On the Changes page, on the Open tab, select and open the ECN for which you want to create an MCN.

  3. In the Change Summary panel, select an object and click Impacted Work Packages .

  4. On the Change Impacted page, in the Impacted by the Change list, select a work package impacted by the change notice, as indicated by a warning indicator , and then click Create Manufacturing Change Notice . Note You can only create one MCN per work package. If a work package is associated to an MCN, Teamcenter Easy Plan will display an error message, and will prevent you from associating another MCN to the work package.
    Note The preference EPC_ManufacturingChangeNoticeType is multi-valued that allows you to add any desired MCN values to it.

  5. In the Create Manufacturing Change Notice dialog box, in the Synopsis and optional Description text boxes, type the preferred text.

  6. Click Create and Submit to create the MCN.

    The work package no longer shows a warning indicator , indicating that the MCN was created and is now linked with the ECN and associated with the work package.

  7. Hover over the affected work package and click Open . The Manage Work Package page opens, with work package details such as structures and tasks.

  8. In the Tasks panel, click the appropriate task.

  9. In the Track Your Work dialog box, do one of the following:

    To set the MCN, accept the default selection, Track with this change notice, and select the MCN you created.

    To skip MCN tracking, select Work without tracking changes.

  10. Click Continue.

    The preferred page opens, with the MCN name displayed as an active change notice above the Change Summary panel, and the affected ECN name displayed below the Change Summary header. Parts or processes affected by the change notices included within the scope of the work package that appear in the ECN are listed below it.

  11. Review notices in the panel and apply any necessary changes to your structure.

  12. In the structure to be changed, select the assembly or subassembly that contains the change and click Revise . The revision updates to reflect the change (for example, revision A changes to B, and B changes to C). If you reopen the MCN in the Open tab of the Changes page, the Elaborating section of the Progress panel displays the effect of the change notice modification.
