The following points are relevant:

  • The Sched. End Date = Sched. Start Date plus Planned Duration.

  • If the Firm Dates is selected the task will not be changed automatically.

  • If the task is completed it will not be changed automatically.

  • If the task is already started the formula changes:
    The Sched. End Date = Start Date plus Planned Duration.

  • The latest scheduled end date of all the steps within the same sequence is the scheduled start date for all the steps of the next higher sequence.

  • Requested start and end dates are only changed if

    • They are entered and

    • The requested start is LATER than the re-calculated scheduled start or

    • The requested end is EARLIER than the re-calculated scheduled end

  • The planned duration may be influenced by office hours. If the Planned Duration is 4 Hours and the office hours are Monday through Friday from 8 am to 5 pm, then if Sched. Start Date is Friday 4 pm the Sched. End Date will become Monday at 11 am. Without office hours to consider this would be Friday 8 pm.

  • Other planned duration units:

    • Days are added in blocks of 24 hours, without looking at the office hours start and stop times. Days on which no office hours are defined, like Saturday and Sunday for example, will be skipped. This means that a 3 day task that starts on Friday at 2 pm will finish on Wednesday 2 pm. Without office hours to consider this would be Monday 2 pm.

    • Weeks are added in blocks of 7 days of 24 hours. Office hours do not play a role.

    • Months are added as a regular months, so a 2 months task that starts April 12 at 3 pm, will end June 12 at 3 pm. Office hours do not play a role.

    • Years are added in blocks of 12 months. Office hours do not play a role.

Office Hours can be defined on the Calendar Groups screen. Create a Calendar Group and then on the Calendar Periods tab add one new period and fill in the relevant start and stop time for each day of the week. Fill in the period (Start Date and End Date) over which these settings are applicable and most important, select the Internal Office Hours checkbox. Once you have defined the calendar group make sure you attach it to the relevant organization on the Organizations screen.
