Undo Changes in Primavera Cloud

Primavera Cloud supports Undo and Redo functionality on several pages throughout the application. Undo is a powerful tool that enables you to revert certain actions and field values to a pre-modified state. For example, if you entered a new duration value for an activity, you can use Undo to revert to the previous value. To reinstate an action or value that was undone, you can use Redo. Up to 50 items are stored in the Undo history. The Undo history is unique to each page that supports Undo.

The following pages support Undo functionality in Primavera Cloud:

• Activities
• Project and Program Resources Assignment List
• Project and Program Schedule Assignment List
• WBS
• Workspace and Project Resource List
• Workspace and Project Role List

To use Undo or Redo:

1. After modifying a value for an object on a page, you can do either of the following:
   • Select  Undo or  Redo.
   • Use the keyboard shortcuts Ctrl + Z to undo an action and Ctrl + Y to redo an action.

     Note: If an action is not supported by Undo or Redo, the icons on the toolbar will be disabled. A confirmation message appears if a proposed action cannot be undone.

2. All changes made to this page are saved automatically.
