How to maintain the summarization of all the projects in P6
Currently I have created one summary project with milestones for management team, whatever i'm updating in the other projects i have to manually update the summary project. Is there any possible to link the projects to summary project so that whenever the changes in the milestones it get reflect in summary project.
eg., Summary Project Named Company
and i have 101,102,103 projects each consists of detailed activities and milestones. if I update them the relavent milestone in Summary should get updated. It will ease my work to share with management.
