Planning console percent complete not updating after parent field reference is modifiedIssue The planning console percent complete is not updating on a project. The following symptoms occur together when the parent field reference in sys_dictionary has been customized away from the base system configuration: The top task field on the project task has an invalid value.The rollup field on the parent task does not update when a sub-task is created.The WBS number on project tasks is not generated automatically.Percent complete does not update when project task values change. Release All Cause A customization was made to the sys_dictionary entry for the parent field. In the base system, the reference field for parent points to the Task table. The customization changed this reference to the Incident table. Because the parent field on project tasks holds a value pointing to a project record, the incorrect reference to the Incident table causes the system to lose that reference. This triggers all of the symptoms listed above. Added context from ServiceNow docs: The business rule Update parent percent complete is responsible for recalculating percent complete whenever a project task is updated. Ensuring all tasks have a valid planned duration and a correctly structured hierarchy is key to resolving incorrect percent complete values on the project record. Tasks with a zero planned duration, such as milestone tasks, do not contribute to the rollup weighted duration calculation, and deeply nested sub-task completions may not propagate correctly up the hierarchy. Resolution To resolve all symptoms, restore the parent field reference in sys_dictionary to point to the Task table. Log in to the instance as a user with the admin role. Navigate to the sys_dictionary entry for the parent field.Confirm that the Reference field is currently set to the Incident table rather than the Task table.Change the Reference field value to Task.Save the record.Verify the fix by opening a project task in the planning console and confirming that the following are now correct: - Percent complete updates as expected. - The top task field displays a valid value. - The rollup field on the parent task updates when a sub-task is created. - WBS numbers are generated automatically on project tasks. Added context from ServiceNow docs: If percent complete still does not update after restoring the reference field, note that KB0867748 documents a Known Error where date updates on a project task do not affect the percent complete of the immediate parent — this is reproducible on the form view rather than the planning console.
