Redlines in Change Orders

Redlines are the individual changes on items and on reference designators that display mark-up. They're indications of recommended, modifications, additions, or deletions (withdrawals).

Any modification to a single item attribute is counted as one redline. The same is true whether you're adding or withdrawing an element to a structure.

Any modification to an existing structure attribute counts as a single redline. So, modifying the content of the reference designator attribute is one redline, and changing a second attribute counts as a second redline.

Redline information for item extensible flexfield attributes are shown in the Additional Information tab, next to the Summary tab. The Additional Information tab appears only when redline information exists for extensible flexfields.

Note: Validations aren't executed on extensible flexfield attributes that aren't redlined in a change order.

Merge Redlines Through Import

You can incorporate redlines coming in through import into existing affected items on a change order. This helps in reducing the number of outstanding changes, stuck changes, and overall change order cycle time. This is supported for engineering change orders and change orders without revision control.

You can import redlines and merge these with existing redlines on engineering items that are assigned to a change order. You can do this as long as the change is in draft or open status. The following modifications can be merged:

• Item general information
• Item structure components
• Reference designators
• Substitute components
• AML

Redlines in Multi-Row Attributes

When you delete a row in an attribute, the row is immediately removed. However after you save the changes, the row appears as redlined.

Undo Redlines

In structures and AMLs, you can undo redlines resulting from addition, deletion, and modification of components and manufacturers

Here's how you undo redlines in a structure.

1. Open the change order and navigate to the item structure page.

2. Select the rows in which you want to undo the redline and click Undo Redline.

   An Undo icon appears against the rows you selected.

   The following screenshot shows the icon against redlines from deletion, modification, and addition:

   

   Note: You can also cancel the undo redline action. Select the row in which you want to cancel the undo action, and again click Undo Redlines.

3. Click Save.

   Note: The undo action is complete only after you click Save.

Troubleshoot Missing AML Redlines

Prior to update 23D, AML redlines weren't being captured correctly on a few change orders because the date attribute values weren't synchronized. From update 23D onward you can run the Upgrade Product Management Data scheduled process to resolve this issue:

To update start date values for AML, run the Upgrade Product Management Data scheduled process with the following settings:

• Upgrade Process: Execution
• Functional Area: Item Relationships
• Feature: Update start dates on AML and display redlines
• Commit size: 10

To see which AMLs need to be fixed, you can run the same job with the upgrade process set as Analysis instead of Execution.
