I am using Project 2010 Pro and administer a number of projects. All projects use the same 'Flags' which are available in my Global.mpt file. However, I have inherited a project file that uses its own customised 'Flags' 1 -5. My problem is that when I open this mpp file its own 'Flags' are replaced by those in my Global.mpt file (along with the formulas for each). Is this behaviour correct? If not what corrective action can I take?
