When the calendar for a resource changes, you must run two processes to update the availability data. You must first run the PRC: Generate Calendar Schedule for a Single Calendar or the PRC: Generate Calendar Schedules for a Range of Calendars administrative process to reflect the new calendar in the schedules of the resources, requirements, and assignments as is appropriate.
Then, you can run PRC: Rebuild Timeline for a Single Resource or PRC: Rebuild Timeline for a Range of Resources to reflect the change in calendar and resource availability in the timeline. This process rebuilds the availability data of one or more resources incorporating changes made to the calendar or schedule.
Note: If you change the value of the profile option PA: Availability Duration from daily to weekly or vice versa, you must run Refresh Resource Availability and Rebuild Timeline for a Range of Resources or for a Single Resource. The processes recalculate the availability of the resource based on the new profile option setting. If a resource has not been scheduled for a long time, say two years, you run either Rebuild Timeline for a Range of Resources or Rebuild Timeline for a Single Resource.
