Work with change notices

Associate a work package with a change notice

To incorporate changes into a manufacturing bill of materials (MBOM), a usage MBOM, or a bill of process (BOP), and to ensure that new changes are tracked using a change notice, you must associate each change notice with the work package that contains the affected engineering bill of materials (EBOM) and other relevant structures.

The Change Impact page lists work packages associated with a selected change notice that are impacted by EBOM changes.

Procedure

  1. In your Favorites, Folders, or other location where you store your assignments, select a work package and click Changes .

  2. On the Changes page, select a change notice and click Open . The Changes page displays a variety of panels and provides a Progress bar that details the selected change's progress (Elaborating, Reviewing, Executing, or Complete). The Change Summary panel tracks the effect of change notices, and shows changes to revision ID, properties, and actions that caused it. Under Revision and editable column properties, added and deleted elements are displayed in green and red.

  3. To locate elements impacted by changes in the Change Summary panel, in the right toolbar, click Impacted Work Packages .

On the Change Impact page, a list of work packages is displayed. The work packages contain structures affected by the changes. A warning next to the work package indicates that it is not yet associated with the active work notice.

  1. From the Impacted by the Change list, select the preferred work package and in the toolbar, click Associate with Change Notice .

The change notice is associated with the work package and its name is displayed in the Active Change Notice column of the Impacted by the Change list. The icon is no longer visible.

  1. In the Change Impact page, select the work package and click Open . Note If you did not associate the work package with a change notice in step 4, a message reports that changes will not be tracked without an association and prompts you to click:

Continue Without Tracking to open the package without tracking in the BOM Alignment page.

Associate and Continue to apply step 4 and to open the work package in the Align page below.

Unless you are using a usage MBOM, the change notice is set to active and the Align page opens with a Change Summary panel showing individual changes in tiles to the left, and the affected structure to the right. In this example, the tiles contain more detail on changes in the context of the parent assembly, including the impact, if any, on an EBOM and MBOM at the bottom of each tile.Note If you are using a usage MBOM, even if you have set an MCN in steps 4 and 5, you must select an active change notice in the BOM Alignment page.
