I am trying to schedule a job to run several times a day.

It's a Utilization job which is part of the FinancialForce PSA application. The UtilizationScheduler class has this signature:

global class UtilizationScheduler implements System.Schedulable {
    global UtilizationScheduler(pse__Utilization_Calculation__c calc) {

    global UtilizationScheduler(pse__Utilization_Calculation__c calc, String cronDayParm) {

    global void execute(System.SchedulableContext sc) {


I think I am close with:

System.schedule('Utilisation 1am 1pm 5pm', '0 0 1,13,17 * * ?', new UtilizationScheduler());

But I get an error: Invalid type: UtilizationScheduler by Executing Anonymous Apex from the Developer Console.

How should I call the UtilizationScheduler Class? How do I tell it what Utilization Calculation (a custom object in FinF PSA) to use?

Apologies - this is my first foray into Apex code. Help greatfully received!

Classes installed from a package have a namespace. To call it, you should use the appropriate namespace:

  'Utilisation 1am 1pm 5pm', 
  '0 0 1,13,17 * * ?', 
  new namespace.UtilizationScheduler()

I'm not familiar with what the namespace for this package is, but you can find it in Setup > Package Manager. Just replace namespace. with the appropriate namespace for the class.

  • Amazing! Thank you @sfdcfox! The namespace is pse (if you care!) I'm now getting the error Constructor not defined: [pse.UtilizationScheduler].<Constructor>. I need to give it the pse__Utilization_Calculation__c calc somehow. Any thoughts?

  • @StevieP you can try to query one from the database, [select id from pse__Utilization_Calculation__c]; or you can create one manually, pse__Utilization_Calculation__c calc = new pse__Utilization_Calculation__c(); Make sure populate any required fields.

  • Boom! pse__Utilization_Calculation__c calc = [select id from pse__Utilization_Calculation__c where Name='MyUtilCalcName'] I owe you a beer!
