Hello. I am trying to schedule "black-out" days for our IT Department. During this time we are still working, however, User Acceptance Testing and Production is totally off limits. Basically, it's a system shut down. I need to reflect this in my project plan, but I can't figure out how. It's not a vacation. I set it up as a new calendar, but I don't know how it would operate. HELP!!!!!!!!!!

If you still need your resources to work on other tasks, then setting non-working time in the project calendar wouldn't work.

If you have created the "outage" calendar, you can assign that calendar to tasks which would normally require your acceptance and production availability. Double click on the task (or select all tasks you need modified and use the Multiple Task Information dialog box) and on the Advanced Tab, select the "outage" calendar. Check off "Scheduling ignores resource calendar" and any tasks assigned that task calendar will automatically move and not be scheduled for work during the outage.

I hope this helps.
Julie

Thank you so much Julie...It is most appreciated. I spent a minimum of 3 hrs trying to figure out what to do for this particular instance.

You're welcome. Sorry for the time spent :-)
