Hi,

It is Finish to Start

Please i still dont get you quite clearly. may be i should frame it this way: a preceding tasks has a duration of 20d and its suceesor has a 6d duration, also i want the successor to start say the 2nd day into the preceeding tasks, should
i give the successor a dependency of -2day finist to start?

Hi,

Indeed that was not quite clear to me.

If you want the successor to start on day 3, then it is SS+2 days
If you want the successor to start on day 19, it is FS-2d

If we still misunderstand each other: it is faster to try it!

You could do a SS link with a *lag* (not lead) of 2 days or you could do it
with a FS link with a *lead* of the predecessor's duration minus 2 days (ex:
if the predecessor is 8 days long, the FS lead time is -6 days, NOT -2
days). Either way is correct, to choose which you use, ask yourself in the
process itself, which end of the predecessor is the determining factor for
the timing of the sucessor, its start or its finish.

Lead time means that successor starts earlier than the link otherwise would
place it, lag time means it starts later than the link would place it.
