(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?
(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

GLAD i COULD HELP
adab,
If ALL activities are linked Finish to Start, then all activities should be on the Critical Path, as there is only 1 path.
The first activity of WBS 1 is linked to the Start Milestone, then all activities linked Finish to Start under this WBS.
If the Last Activity of WBS 1 is linked to the First Activity of WBS 2 & this sequence is repeated through all the WBS Levels, with the last activity of WBS 7 being linked to the Finish Milestone, then there is 1 path so all activities will be critical.
If the WBS Activities are linked as shown in Jithin's post & the total duration of each path is the same then all will be critical, as you may have 7 different paths from the Start Milestone to the Finish Milestone - The Float for each path would be the same & all activities would be driving the critical path.
If 1 activity took longer during execution, then this path would become the critical path.
If you increase the duration of 1 activity, do all activities remain critical, or is a new critical path identified?
Do you have any constraints applied on your Project?
Steven
adab,
Am I misreading your last post:
"Is it possible that even in a small project of primavera having 5 or 6 activities all in Finish to Start relationship, All activity will become red in ghant chart?"
If ALL activites are linked Finish to Start in a small project, then ALL would be Critical & Red in the Gantt Chart.
Are there any relationships between the different WBS?
Steven
if you have a constraint date or a project must finish by date that will dtermine the criticaally of it.
if EVERYTHING is FS then depending on the duration it wil dtemeine the critical path
Hi Adab,
May be all the Activity under Different WBS on FS relationship has equal dutation and is pushing the Finish Milestone then all the activity would be Critical. Check that too.
| WBS | Activity | Duration | Total Duration | Float to Finish Milestone | ||
| WBS 1 | Activity 1 | 2 | 14 | 0 | ||
| WBS 1 | Activity 2 | 4 | ||||
| WBS 1 | Activity 3 | 8 | ||||
| WBS 2 | Activity 1 | 5 | 14 | 0 | ||
| WBS 2 | Activity 2 | 6 | ||||
| WBS 2 | Activity 3 | 3 | ||||
In this all the Acivity would be Critical if under FS relationship.

Jithin
Hi Adab,
Look at the Project - Must Finsih Date and then go to Settings of the Project and check what has been selected for "Define Critical Activities.
If you have selected " Longest Path" then the longest path in your schedule would be Critical.
If you have selected "Total Float less than or equal to" - No days - All the activity which has a total float less or equal to that duration would be critical.
Regards
Jithin
