I just tested this scenario stated by NISHIL, and it worked exactly as you would expect. I have run into the problem as stated by "-weak architect" so he probably has loads of experience to recognize this.
After you verify that I think you should have it. You can always import the schema and map from the other project but I'm sure this would be a waste of time. If their suggestions don't work…which they obviously should, then I would recommend either deleting and replacing the functoids, or create a new map to test that one scenario. It only took me a few minutes to set this up with a project open already.
