Juliano. I was also working on a 24 hour task when I read your post.
1. Set project calendar to 24 hours 2. Set timescale middle tier = days bottom tier = hours 3. Generate tasks for the appropriate shifts (I used 3 – 8 hour shifts) 4. assign resources Summary: 48 hour task started at Friday at 3:30pm and ended on Sunday at 3:30pm = 48hours
Send me your email and I’ll send you the project plan (2010)
