I just started to use this program and I wanted to ask you this:
I am two or more activities (fixed units) starting at different times (the start is governed by various predecessors). I would like to set the duration of activity number 03-05-18 and 15 we all have the same duration of activity 2. without changing the predecessors.
Andrea, sorry but I can’t understand the question. Setting duration the same on multiple tasks is pretty simple and has nothing to do with predecessors. Use the duration field, not the start or finish. If that doesn’t help then please provide more details and I can see if I can help.
Not really. There is a feature called Hammock Tasks that can do this but it is highly recommended not to use in general (not very stable). I’m only mentioning this in case you run across this somewhere and want to try it.
