try to complete that task

After inserting a new candidate record, candidate may insert wrong date in the field “Application Date”. Write a trigger so that every time a new candidate record is created in a system, an “Application Date” field would have a value as system generated CreatedDate field of that record only and not using any Date functions.

Hi Krishan,

We cannot use Created date in before context because created date will be calculated once the record is saved to database. In case of after context as the record will be in read only mode so it cannot be achieved in the after trigger as well.

The best option would be using the Today date as the record creation date will be always equal to Todays date.
  
trigger ApplyDate on candidate__c (before insert) {
    for(candidate__c cb: Trigger.new){
 cb.ApplicationDate__c = system.today();
    }
}

If this solution helps, Please mark it as best answer.

Thanks

Hi Krishan,

Please try the below code:
  
trigger ApplyDate on Candidate__c(before insert){
	for(Candidate__c cb : Trigger.New){
		if(cb.ApplicationDate__c != system.today()){
            cb.ApplicationDate__c = system.today();  // anyway both created date and today will be same.So you can use today date itself. 
        }
	}
}

Thanks,
