To access Gantt Settings within the Process Designer, navigate to the "Actions" menu item and select "Open Process Settings." Then, navigate to the Gantt Settings tab (1):

The following settings may be modified on the "Gantt Settings" tab:

• Calculate dates before starting the process (2) - If checked, a Planned Record will be created when the Process Instance is created. This Planned Record will have Planned Start and End Dates calculated for each (active, pending and future) step. These are actual dates for "Date Driven" calculation modes (4). In "Duration Driven" calculation mode, dates are shown for estimation purposes only and are not saved.
• Calculate durations (3) - When checked, step durations that are defined as expressions will be pre-calculated and static in the Gantt chart. Otherwise, durations will be shown as formulas and calculated dynamically each time you open the Gantt chart of a planned or started record.
• Default calculation mode (4) - Select how future steps' dates will be updated when a date/duration of a preceding step is changed. See the dedicated knowledge article to learn more.
• How to handle manual date changes (5) - Select how steps should behave when their dates will be changed.
