Apex Code to create recurring event salesforce

Question

Can anyone provide me sample apex code to create recurring event in salesforce.

I am using below code:

Event newEvent = new Event();
newEvent.OwnerId = '023170000004yO9AAI';
newEvent.Subject ='Test';
newEvent.WhatId = recordId;
newEvent.IsRecurrence = true;
newEvent.RecurrenceStartDateTime = System.today();
newEvent.RecurrenceEndDateOnly = System.today()+30;
newEvent.RecurrenceType = 'RecursDaily';
newEvent.IsAllDayEvent =true;
newEvent.DurationInMinutes =1440;
newEvent.ActivityDate = yagyaPerformanceObj.Start_Date__c;
insert newEvent;

I am using above code to create recurring event. My requirement is to create recurring event for 30 days which recurs daily. I am getting this error 'REQUIRED_FIELD_MISSING, Required fields are missing: [Recurrence Interval]: [Recurrence Interval]'

I don't know which field I am missing.

Answer 1

See the salesforce documentation on the Event object.

It looks like you are trying to do a 'RecursDaily' type of event. According to the documentation above (and in particular the table located at the bottom of the page), that means you should also be populating the RecurrenceInterval field.

So your code would be:

Event newEvent = new Event();
newEvent.OwnerId = '023170000004yO9AAI';
newEvent.Subject ='Test';
newEvent.WhatId = recordId;
newEvent.IsRecurrence = true;
newEvent.RecurrenceStartDateTime = System.today();
newEvent.RecurrenceEndDateOnly = System.today()+30;
newEvent.RecurrenceType = 'RecursDaily';
newEvent.RecurrenceInterval = 1; // This means that the event will wait 1 day before recurring again
newEvent.IsAllDayEvent =true;
newEvent.DurationInMinutes =1440;
newEvent.ActivityDate = yagyaPerformanceObj.Start_Date__c;
insert newEvent;

Not sure what your expecting .. Edit your question?

trigger ClassTrigger on Class__c (after insert) {
Map<String, Class__c> clasMap = new Map<String, Class__c>();
// after Classes are inserted
   List<Event> followupEvents = new List<Event>();// build list in memory
   for (Class__c clas : System.Trigger.new) {
    date t = clas.Start_Date__c;
          datetime xStartDate = DateTime.newInstance(t.year(),t.month(),t.day());
   Event event = new Event(
    ActivityDate = clas.Start_Date__c ,
    RecurrenceEndDateOnly = clas.End_Date__c ,
    RecurrenceStartDateTime = xStartDate,
    RecurrenceType = 'RecursEveryWeekday',
    RecurrenceDayofWeekMask = 1,
    IsRecurrence = TRUE,
    Description = 'Class Event.', 
    Event_Type__c = 'Customer Training',
    Call_Objective__c = 'training',
    Location = clas.Facility__c , 
    IsAllDayEvent = TRUE, 
    Event_Status__c = 'Not Started', 
    Subject = 'Class trigger Event');
  followupEvents.add(event);  // add to list
   }
