Tips on using this forum..

(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.

94. Non-overlapping Lag Relationships. This check entails looking for lags or Leads greater in duration than the Activity Duration. Lags and leads typically are used to allow related activities to overlap in time. When the lag is larger than the activity duration, this overlap condition no longer exists and the reason for using the SS or FF relationship disappears. If the lag used is too great, the activities will no longer overlap in time. This may be an entry error. Otherwise, I suggest that you convert to a different relationship that better describes the intended relationship. Suggest that you investigate converting to a standard FS relationship.

Dear Shahul,

Planning Phase: The lags are used to reflect actual requirements at site.

Scheduling: The software nowadays are flexible to a large extent.

Basically, you need to write up your schedule to avoid the lag and use simple relationship.

With kind regards,

Samer
