Update Baseline dialog box

Use the Update Baseline dialog box to update project- and activity-level data types for the baseline you selected in the Maintain Baselines dialog box.

The dialog box includes these tabs:

Default: Click to reset all the options to their defaults.

Preview: Click to open the Preview Changes dialog box.

Update: Click to update the selected baseline's data with new, modified, or deleted data from the current project.

Tip:

To overwrite all activity data, choose All Activities and all of the activity data options.
To update project-level data only, select the 'Project details' option and clear the add new, delete, and update activity options. Clearing the activity data options causes no activity data to be updated, regardless of whether the All Activities or Activities Within the Following Filter are selected.
If errors occur when updating a baseline in optimized mode, you will not be able to determine the activity that is causing the update to fail. To determine the activity causing the failure, turn off the Run Optimized option and rerun the baseline update. If you are connected to an EPPM database, after the update is complete, refer to the log file to determine which activity is causing the update to fail.
Note:
When you choose to update project details, the following items are not updated: all data in the Project Properties Defaults, Settings, and Resources tabs, and the Default Price/Unit for activities without resource Price/Unit field in the Project Properties Calculations tab.
Project, WBS, and issue UDFs are updated only if you select the option to update them.
