Activity cannot finish until another - zero float

Two ways to try:-



1. Activity A 20days FF to Activity B 2 days then reschedule changing Schedule Durations option from Contigous to Interruptible and back (found in Tools, Schedule, Options). No percentage option in P3 but you could put -10 days lag on the FF.



2. Activity C 10 days FS to Activity D 10 days and Activity E 2 days with FS between E and D. Put Zero free float constraint on E.



No a big fan of FF so I tend to use method 2 and define what needs to happen before E is required and then what can happen once it has arrived.

Can you please elobrate on " no earlier than"?



Also the schedule i’m putting together doesn’t have resource contraints just time contraints. Does this help?



Is there a way to get P3 to behave to get JIT?

It is not supported if resources are limited.

All dependencies used in Primavera software are of "no earlier than" type.



The dependencies you need (JIT) are called "strong dependencies" in Spider Project software.
