Gantt update actuals

The ALLOW_GANTT_SCHEDULER_UPDATE_ACTUALS property controls whether the Gantt scheduler updates actual field values based on planned dates and completion percentage, with TRUE as the default legacy behavior.

See also Gantt milestones and planned tasks.

If you set ALLOW_GANTT_SCHEDULER_UPDATE_ACTUALS=FALSE in the TRIRIGAWEB.properties file on the Maximo® Real Estate and Facilities server, the Gantt scheduler does not update the actual field values if the Actual Start date is > 0. If the Actual Start date is not set, the default behavior is followed.

When the property is set to TRUE, the Gantt scheduler updates the Actual Start, End, Working Hours, and Duration values based on the Planned Start date and Actual Percent Complete fields. This business logic is similar to that in the task forms.

The default is TRUE, which reflects the legacy behavior. See the following algorithm:

  • If Actual Percent Complete = 100%, set Actual Start, End, Duration, Working Hours to Planned Start, End, Duration, Working Hours.
  • If Actual Percent Complete > 0%, set Actual Start, End, Duration, Working Hours to Planned Start, 0, 0, 0.
  • If Actual Percent Complete = 0%, set Actual Start to Planned Start if Actual Start > 0, or else set Actual Start to 0, and set Actual End, Duration, Working Hours to 0, 0, 0.
Note: The ALLOW_GANTT_SCHEDULER_UPDATE_ACTUALS property was introduced in IBM® Maximo Real Estate and Facilities 3.5.2.3 and 3.5.3. For 3.5.3, this property is available in the TRIRIGAWEB.properties file. For 3.5.2.3, this property is supported, but your application administrator must add the property to the TRIRIGAWEB.properties file.
