If you are manually editing the ProDOC.def file on your local workstation then you will need to place the file into the Control folder on the central server. This will send the new prodoc.def file to each work station the next time they login/logout.

If you are editing it via ProDOC when you save it, the changes will be placed on the central server as well as the local workstation and other users will receive the changes once they login/logout.
