Hi Larry, Happy New Year 2016. I tried the steps in Project 2013 Pro. Please take a look at this picture https://i.imgur.com/ysZO6Ss.png. I have two tasks – one is 100% and other is 50% complete. When replacing the 100% tasks with another resource, the actual work is moved to the new resource. When replacing a inprogress task with another resource, the actual work is not affected but the remaining work alone is moved to the new resource – see this picture https://i.imgur.com/kEJ2qAq.png. I can understand that Alfred is looking for an option to replace resource such that the actual work and remaining work is moved to the new resource, which can’t be done.
