Project task % completion auto update

[Scotty88]

I require the Project task % completion auto update based on planned and actual effort, I have the following BR however thins is not working, % completion remains unchanged when I have values for planned and actual effort, has anyone done this?

BR details:

• Table: Project Task [pm_project_task]
• When: After
• Insert: True 
• Update: True

Condition:

• Condition: Actual Effort changes

(function executeRule(current, previous /*null when async*/) {
    // Calculate total planned and actual effort for the project
    var projectGr = new GlideRecord('pm_project');
    if (projectGr.get(current.project)) {
        var totalPlannedEffort = 0;
        var totalActualEffort = 0;
        
        // Calculate the total planned and actual effort for each task
        var taskGr = new GlideRecord('pm_project_task');
        taskGr.addQuery('project', current.project);
        taskGr.query();
        
        while (taskGr.next()) {
            totalPlannedEffort += taskGr.planned_effort;
            totalActualEffort += taskGr.actual_effort;
        }
        
        // Update project percent complete based on actual vs planned effort
        if (totalPlannedEffort > 0) {
            var percentComplete = (totalActualEffort / totalPlannedEffort) * 100;
            projectGr.percent_complete = percentComplete;
            projectGr.update();
        }
    }
})(current, previous);
