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.

There are two other options for lags:

Elapsed lags, say FS+10edays will give you an elapsed lag ignoring the Successor calendar.

Percent Lags, say FS-50% which will allow the successor to start 50% through the duration of the predecessor.

P3 and SuerTrak use the predecessor calendar but Primavera Enterprise gives several options.

In MSP 2003, working days in lag relationships are computed based on the Successor Activity’s calender. This defaults to the Project Calendar if no other calendar is specified for the successor activity. (I think P3 uses the Predessesor’s calendar).

[This is a correction I just learned today, so I thought I’d post it for the record.]

I have been told that MS Project lags are calculated using the Default Calendar.
