Primavera P6 has a built-in operation called Dissolve Activity that allows us to delete an activity without deleting its Relationships;.

 

The following example shows how Dissolve Activity works in Primavera P6. 

 

  • I have a project with three activities. The A1 successor is A2 & the A2 successor is A3. The relationship type between these activities is  Finish-to-Start. Look at the Gantt Chart

  • I dissolved the Activity A2 by Right click on it and select Dissolve; The Activity A2 will get deleted.

  • I Scheduled the project; A1 is now linked to A3 automatically. Look at the Gantt Chart again

Tha above example shows a simple approach of dissolving an activity. In actual P6 project implementation, An activity is linked to many activities, that is an activity may have many predecessors and successors; When an activity get dissolved,  P6 creates a new relationship by the first part of the predecessor relationship and second part of successor relationship. For Example:

 

Predeccessor Successor New Relationship
Finish-to-Start Start-to-Finish Finish-to-Finish
Start-to-Finish; Finish-to-Start Start-to-Start
Start-to-Start; Start-to-Finish Start-to-Finish
Start-to-Start; Start-to-Start Start-to-Start
Finish-to-Finish; Start-to-Start Finish-to-Start
