When you are referring to when the schedule is "live", are you referring to when a project timeline has already started (meaning tasks have already been completed for a few steps) or when the project is changed from Draft to Current? I am not sure understand the definition in this case to fully be able to help.
Hi @kierstenkollins & @alexa_m_psu, I'd check this setting not only in your project preferences in setup but also in your project templates. Whatever is set in your project templates will override the setting in setup.
We don't use this setting either (ignore time off) bc we don't have the luxury of modifying a schedule based on resource availability, we put a different resource on it. In terms of it shifting after a project is created, I've found that it if you do have the setting to consider time off, it only considers it at time of project creation and IF the users have the time off already in place in Time Off. After it's in Current, say someone then adds Time Off during when they have tasks due, I haven't found it slides those existing task due dates. But if they log time off and THEN you create a project with tasks during that timeframe, the dates will move around it.
For these reasons plus the one I initially mentioned, this setting just doesn't work for us or for other orgs I've worked with. I don't use it too often because of this, but this was my experience in the past with shifting/not shifting that confirmed my choice to turn it off. If your org doesn't use Time Off in users' profiles, and you have this setting on to consider time off, than it's irrelevant and doesn't matter.
