Dissolving Activities

You can dissolve an activity to remove the dissolved activity and join the predecessor and successor activities to maintain the project's network logic. You cannot dissolve an activity unless it has a predecessor and successor. You can only dissolve one activity at a time.

To dissolve an activity:

  1. Click Projects.
  2. On the Projects navigation bar, click Activities.
    1. Select a single activity and click Actions  and select Dissolve.
    2. In the Confirm dialog box, click Yes.
    3. Click Save.

Tip

By default, any lag applied to relationships with the dissolved activity is removed and the new relationships created have zero lag. However, you can select Retain lag in the General section in the Global tab of the My Preferences page if you would prefer to keep the lag applied to predecessor and successor relationships when you dissolve an activity. If you choose to retain lag, the lag from the predecessor relationship is added to the lag from the successor relationship and applied to the new relationship.
