When you update a project, the baseline and tasks on the project grouping are updated. However, there might be times when you do not want to update the baseline and tasks.
For example, developers might not want any new tasks if they are conducting unit testing but must pick up a dependent change from another developer.
Build managers might not want to get any new tasks if they have
done an update but must add a task to fix a build.
The baseline and tasks are a part of the project grouping. If you do not want the baseline and tasks to be updated, clear the update option in the project grouping that the project is in.
Procedure
In the Projects explorer, right-click over the appropriate project grouping and select Automatically Update Baseline & Tasks. This option clears the check mark to the left of the option. Additionally, if you start the Properties dialog box for the project grouping, notice that the Auto Update check box is cleared. It remains cleared until you select it or right-click over the project grouping in the Projects explorer and select Automatically Update Baseline & Tasks.
