You can use the MicroStrategy "Object Manager" tool to copy objects from one project into another. You can also use a new wizard if you have a more recent version of MicroStrategy Object Manager (v 7.2) called the Project Merge Wizard. I haven't done it, but according to MicroStrategy's documentation, see technote TN6600-072-0022, it appears that you can merge two projects into one using that wizard as well. HTH,
