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 of time, 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 that:

• 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 either,
  • define an alias before you map an overlay calendar to an organizational entity, or
  • define an alias when mapping an overlay calendar to an organizational entity. See Calendar Aliases (References).
• 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 ActiveMatrix BPM uses the latest calendar mapping so you should make sure that if you do remap a calendar while a process is deployed, that it does not adversely affect the process.
