(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?
(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.
Thanks Guys,
Yes normally I open both projects together and then copy and paste the WBS over but that was messing up my Activity IDs.
Thanks Rodel, I have just started using the new version and didnt realise you get those options with only one project open!
Cheers,
Tom
