Renumber Activity IDs

You can quickly renumber a group of activity IDs based on a repeatable pattern. Choose to increment individual IDs by a specific numeric value, auto-number IDs in sequence based on a prefix and number pattern, or replace the beginning characters of all selected IDs with the same value.

If the option you choose causes duplicate activity IDs, you will be prompted to enter a new activity ID for each conflicting activity. You can also cancel the process and try again with a different pattern that does not cause duplicates.

To maintain consistent activity IDs across baselines, you can choose to renumber the selected IDs in the current schedule and all of your project's baselines. If renumbering the IDs will cause duplicates in any baselines, you can either cancel the renumbering process or update the current schedule and any baselines where duplicates will not occur.

To renumber activity IDs:

  1. Navigate to the Activities page
  2. Select one or more activities, select the Context menu, and then select Renumber Activity IDs.
  3. In the Renumber Activity IDs dialog box, choose one of the following options:
    • Increment Activity ID based on selected activities: Enter a value that each selected activity ID will be incremented by.
    • Auto-number: Enter a prefix value, starting number, and increment value. The selected activities will be updated in the order that they were selected.
    • Replace beginning characters: Enter the number of characters to replace starting from the beginning of the ID, and then enter the value that will replace the characters.
  4. Select Renumber selected activities in baselines if you want to also renumber the selected IDs in any baselines where they appear. This option is only displayed if your project has at least one baseline.
  5. Select OK.
  6. All changes made to this page are saved automatically.
