The proper way to maintain a baseline for this situation is to add the additional tasks for the chage, note and tasks that have been extended as a result of the change, select those tasks, set baseline for selected tasks, and rollup baseline to summary tasks. You should do this to your current baseline (not create a new baseline). This process doesn’t specifically itemize the tasks that were part of the original variance vs the tasks that were reflected by the change request but that can be managed through a custom descriptive field. But, those tasks already started are part of the original variance and those future affected tasks are included in the change request. Hope that helps…
