hi,

For schedule tracking purpose, i wan't to create two timelines for each project one as "Planned baseline" and he other as "Actual baseline",

the Planned timeline must be like "Readonly " or reference timeline  and the "actual baseline" will changes (by the project admin certainely) as the project progresses

actually i'm doing this with duplicating the whole project (attached picture) but it's not a good solution 

Any idea ?

Please reply
