Overlay Calendars

Overlay calendars define non-working time exclusions (for example, public holidays) which can be applied to one or more base calendars at runtime. You should use overlay calendars for exclusions that are repeated over a defined period, like a regular company meeting.

An overlay calendar is timezone-neutral, and so inherits the time zone from the base calendar it is applied to.

Note the following considerations before using the Overlay Calendar:

  • You must map an overlay calendar to an organizational entity.
    Note: Overlay calendars cannot be mapped to resources.
  • Overlay calendars are mapped to organizational units using their alias. You can define an alias either,
    • before you map an overlay calendar to an organizational entity, or
    • when mapping an overlay calendar to an organizational entity.
  • An overlay calendar can be mapped to multiple organizational entities.
  • An organizational entity can only have one overlay calendar applied to it at any time.
  • You can remap an overlay calendar to a different organizational entity at any time.
    Note: TIBCO BPM Enterprise uses the latest calendar mapping. So if you remap a calendar while a process is deployed, then it does not adversely affect the process.
