Backward Schedule (Is it possible?)

Backward Schedule (Is it possible?)

Backward Schedule (Is it possible?)

I am having a problem with the following:

    Task 1
    Task 2

Task 1 will start after Task 2 is complete.  I would like to create a sort of backward FS (Task2>Task1). Question:   Is this possible w/o moving Task 1 below Task 2 and creating a FS relationship.  Moving Task 1 below Task 2 would create a problem with the layout (presentation) of the schedule.

Any help with this would be greatly appreciated.


RE: Backward Schedule (Is it possible?)

Why didn't you just try it?  

MSP doesn't care what order the tasks are laid out relative to the predecessor/successor relationship.

RE: Backward Schedule (Is it possible?)


I have tried this in the past and was unsuccessful.

To be more specific:

1.0 Engineering
  Complete As built Drawings (15days) “start date to be determined by relationship”

2.0 Commissioning
  Commission Plant #1 (10 days) Mar 01 to Mar 05
  Commission Plant #2 (10 days) Mar 20 to Mar 30
  Commission Plant #3 (10 days) June 30 to July 20

I would like to present the above as is on the schedule.  I do not want to put the Engineering summary underneath the Commissioning summary.

As it stands now, as built drawings can only start after the last commissioning task (i.e. in this case Commission Plant #3) which would begin on July 21 and take 10 days to complete.

When I try to complete a FS relationship between C. Plant #3 and C. As built drawings the relationship shows the link arrow from Complete As built drawings to Complete Plant #3 rather than the other way around.

If this relationship is possible:  Is it possible to link all commissioning activities to the Complete As built drawings so by default the Complete As built drawings would start after the finish of the last commissioning activity.  This would be important during the project if Plant #1 became  the last commissioning activity as opposed to Plant #3 OR is this something that the planner has to manually adjust if the sequence of activity changes

RE: Backward Schedule (Is it possible?)

The relationship is possible.  You're doing something wrong.

If last commision is line 10 and drawing is line 4, then line 4 should have 10FS in predecessor.  Works every time.

RE: Backward Schedule (Is it possible?)

Thank you very much for help.  It worked great but I had to manually type the 10FS relationship in the predecessor text box.  Is there a way to use the FS button to establish this relationship?
