(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.
Dear Family Members
What is the maximum and minimum Lag allowed in a program??
What is the maximum Activity duration can be allowed in a program??
What is the maximum and total float allowed in a program ??

There are no such thing as a universal rules for planning, the rules shall be used only as a guide/warning on possible errors but not to define them as definitive error. Some of these rules might prevent you from creating better models.
Say concrete placing activity takes 6 hours but curing shall start after the 4th hour; there is a necessary lag that is more than 50% the duration of predecessor. You can bypass such 50% requirement if model lag as an activity.
Say an activity takes 3 months, common in linear jobs; if you split the activity into separate activities then resource leveling might spread them apart instead of keeping the activity contiguous.
Float is a calculation, if the software can do the right calculation and the model is good it will be whatever it comes to be.
Hi Arun,
1. For SS+ Lag, the lag should not be more than half of the predecessor duration. Always try to avoid FS+Lag.
2. Try to limit the construction activities in 21 days, to monitor & control it properly.
3. Total Float depends on the proper logic in the programme.
