Review active or closed changes for a structure

You can track changes (added, modified, replaced, revised, or deleted) to the assemblies using a change request or a change notice. When the ECN or ECR is an Active change, redlines are shown in the structure. To view the closed changes, use the Show Redlines command.

Prerequisites

Your administrator can configure the various methods to effectively track and display relevant changes to an assembly.

Procedure

1. Search for and open the structure. If the structure has changes, they are indicated by redlining. Expand the assembly to view the details of the change.

   You can also open the structure in the alignment view in which the design structure and its aligned engineering BOM are displayed side-by-side. In this case, enable the Show Redlines command.

   • Deleted parts are indicated by a red strikethrough.
   • The added parts display in green and are italicized.
   • For replaced or revised parts, the old and the new values are shown side by side.
   • After the structure is revised, the redlines are shown for all changes including the edits that you make for the part attributes.

2. (Optional) To disable highlighting the changes in the structure, go to More Commands > View icon and turn off Show Redlines from the Page level toolbar.

   If you are in the alignment view, disable the Show Redlines command to stop the changes from being highlighted.

3. Only active changes are shown by default. To view the closed changes, open the design structure or engineering BOM in a separate window and click More Commands > View > Show Redlines from the Page level toolbar.

You can return a redline change back to its original impacted version by reverting the BOM modifications.
