Use the Renumber Activity IDs dialog box to specify how to renumber selected activity IDs in the current project and, if applicable, to renumber the same activity IDs in all applicable baselines for this project. The selected activities can be renumbered based on values you specify.
Increment Activity Based on Selected Activities: Select to increment activity IDs using the increment value you specify. For example, suppose you select activity IDs AB100, AB130, AB150, AB160, and AB180. If you type 100 in the Increment Value text field, the selected activity IDs are renumbered AB200, AB230, AB250, AB260, and AB280.
Note:
- Increment Activity Based on Selected Activities renumbers selected activity IDs in the order from largest to smallest. So in the example above, activity ID AB180 is first renumbered to AB280, then AB160 is renumbered to AB260, and so on. If P6 Professional detects that it would renumber a selected activity ID to an activity ID that already exists, exclusive of those you selected, then the Duplicates dialog box appears. You use that dialog box to enter another activity ID.
Auto-Number: Select to renumber activity IDs using the criteria you specify. For example, suppose you select activity IDs AB100, AB130, AB150, AB160, and AB180. If you type AB in the Prefix text field, 100 in the Suffix text field, and 10 in the Increment Value text field, the selected activity IDs are renumbered AB100, AB110, AB120, AB130, and AB140.
Note:
- Auto-Number renumbers selected activity IDs based on the sort order of activities in the activity table. The first activity in the sort order is renumbered using the values you type in the Prefix and Suffix text fields. The remaining selected activities are renumbered using the same suffix and prefix, and they are incremented using the value you type in the Increment Value text field. If P6 Professional detects that it would renumber a selected activity ID to an activity ID that already exists, exclusive of those you selected, then the Duplicates dialog box appears. You use that dialog box to enter another activity ID.
Replace Beginning Characters: Select to replace the beginning characters of the selected activity IDs with the characters specified in the Replace With text field. Type the number of beginning characters to be replaced in the Number of Characters text field. For example, suppose you select activity IDs AB100, AB130, AB150, AB160, and AB180. If you type 3 in the Number of Characters text field and CD5 in the Replace with text field, the selected activity IDs are renumbered to CD500, CD530, CD550, CD560, and CD580.
Note:
- If P6 Professional detects that it would renumber a selected activity ID to an activity ID that already exists, exclusive of those you selected, then the Duplicates dialog box appears. You use that dialog box to enter another activity ID.
Renumber Selected Activities in Baselines: Mark to renumber the selected activity IDs in all applicable baselines for this project. (P6 Professional does not renumber activities in baselines where duplicate activity IDs would be created.) Be aware that if you clear this checkbox, all renumbered activities are disconnected from the baselines and are treated as new activities.
When this checkbox is marked, P6 Professional searches for baselines where duplicate activity IDs would be created. If it finds none, then the current project and its associated baselines are renumbered, and the baseline renumbering is committed to the database with no chance for you to undo the renumbering. If P6 Professional identifies baselines where duplicate activity IDs would be created, then P6 Professional lists those baselines and presents you with a yes or no choice (in the Baseline Duplicates dialog box) whether to continue renumbering.
Notes:
- This checkbox is disabled if no baselines exist for the project.
- If you do not mark the Renumber Selected Activities in Baselines checkbox, you can subsequently update the baselines to reflect the new activity IDs, but you need to be aware of the following: Because the renumbered activities are treated as new activities by the update baseline tool, you must select the Add New Activities and Activity Data (Except Actuals) and the Delete from Baseline Any Activities No Longer in the Current Project options in the Update Baseline dialog box to add the new renumbered activities to the baseline and to remove the original activities. Doing this updates the baseline with the renumbered activities, but the activities will have the current data in the baseline, rather than the original activity data.
