There are two options for scheduling in workflows: baseline and up-to-date.

Baseline scheduling

You use baseline scheduling when you want to compare actual dates to fixed target dates. With baseline scheduling, you never change the target dates, allowing them to serve as a baseline. Users who are assigned tasks receive reminders on completing the actual/forecast dates.

While you work with a baseline schedule, the owner of the Advanced List, On-demand Campaign, or Corporate Campaign sets the initial Target Start and End dates for each task. These dates stay fixed throughout the entire workflow. As the List, On-demand Campaign, or Corporate Campaign progresses, the owner can update the actual/forecast dates with real data based on status information received from team members.

Up-to-date scheduling

You use up-to-date scheduling when you want to use actual dates to update the official schedule (defined by the Target Start and End dates) regularly. This mode enables project managers to capture the most up-to-date, official schedule; however, it does not provide an easy way of viewing a baseline version of the schedule.
