P5 Scheduling Options?

P5/P6 does not support the Interruptible CPM calculation technique as P3 does. It only works as the P3 Continious setting.

Also the Total Float for multiple projects in P5 is correct per project only. P3 has the Advance Scheduling option of “Base float end date when scheduling” and selecting either “project group” or “each project”. P5 uses the “each project” option and there is no “project group” option. I have raised this with Primavera as an incident they have confirmed it does will calculate the “project group” option. One way I have found to do get the Total Float to calculate based on the last activity of multiple projects is to:
- Open the project
- Select the default project.
- Calculate the schedules when they are opened together. You have to manually change all the projects Data dates manually.
- Identify the early finish of all the activities.
- Set a Project Must Finish by Date in all projects.
- Recalculate the projects.
It may be possible to do something with a linked Milestone in each project but I have not attempted this yet.
Therefore Primavera Version 5.0 does not have the options to handle multiple subprojects that P3 has.

Thanks for the heads up Paul, very informative. I suppose the ’lag drag’ issue isn’t addressed in P5 consequently.

No it has not, but I feel this will happen with most CPM software.
