(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.
Kannan,
>there any option to change the relationship between activities quickly, for eg: from activity A, there are 50 activities as successor with FS relation. How the relationship can be changed to SS+5 in a easy way.
You can do this trick:
a) Change activity A to a milestone, and keep existing logic.
b) Add activity B with the original duration of activity A. Add B (SS+5) -> A dependency.
Don't forget to add another successor to 'B' as it will have an Open End - no activity depending on the completion of activity B.
