To dissolve an activity, you select the activity and then choose Edit, Dissolve.
Dissolving an activity removes the dissolved activity and joins the dissolved activity’s predecessor and successor activities as well as possible to maintain the project’s network logic, as explained here. You cannot dissolve an activity unless it has a predecessor and successor.
When an activity is dissolved, relationships are made as follows:
For example, say that Activity A is the immediate predecessor of Activity B, that Activity A has a Start to Finish relationship with Activity B, and that Activity B is to be dissolved. When Activity B is dissolved, all of A’s relationships with B’s successors (with which B had a relationship) must begin with Start.
To continue the previous example, say that Activity C is the immediate successor of Activity B, and that Activity C has a Finish to Finish relationship with Activity B. As Activity B is dissolved, the second half of its relationship to C (C’s end of it) is used and combined with A’s first half of its relationship with B, giving a Start (from A’s side of the A to B relationship) to Finish (from C’s side of the B to C relationship) relationship.
The same principle applies to any other successor activities to B.
So, for example, the following activities have the following relationships:
Activity A is linked to Activity B using SF
Activity B is linked to Activity C using FF
Activity B is linked to Activity D using a FS
Activity B is linked to Activity E using SF
Activity B is linked to Activity F using SS
When you dissolve Activity B, the following occurs:
Activity A is linked to Activity C using SF
Activity A is linked to Activity D using SS
Activity A is linked to Activity E using SF
Activity A is linked to Activity F using SS
