I am insert various projects into a single "Master Project"

Each individual project has its own Baseline. The insert tool doesn't see to transfer across that kind of data.

How can i go about effectively tracking Baselines from within a Master Project without wiping the history every time i add a new one?

Hi Stuart

Thank you for the question

This is rather puzzling because there is no reason why the baseline information should not copy across into your master project. You cannot create a baseline in the master project, but must create each project's baseline individually;but I understand this is what you are doing.

There may be an issue with your installation of project. can I suggest you copy the files to another machine and try creating a master there. if it works then that suggests you need to reinstall project on your machine.

If it doesn't let me know and we can look at other options

Regards

Stephen
