Hi Anupam,

I'm already given my third trigger code on object Candidate_Task__c.
Please find the below two triggers. Please help me to comebine these three triggers.


1. updateEmployeeField


trigger updateEmployeeField on Candidate_Task__c (before insert, before update) {
    System.debug('test');
    if(Trigger.isUpdate) {
        List<Id> resourceIds = new List<Id>();
         //Populate a list of all related cases
         for(Candidate_Task__c cs : trigger.new)
         {
              resourceIds.add(cs.Project_Resource__c);
         }        
         if(resourceIds.size()>0)
         {    
          //Query those resurces
              List<Project_Resource__c> resources = [Select Id, Candiadate_user__c from Project_Resource__c where Id in: resourceIds];                                                         
             //Create a map
              Map<Id,Project_Resource__c> resourceMap = new Map<Id,Project_Resource__c>(resources);
              //Update the Project_Resource__c objects
              for(Candidate_Task__c cs : trigger.new) {
                   //Only process if there's a case mapped
                   if(resourceMap.containsKey(cs.Project_Resource__c)) {
                        //Set the values
                        cs.Employee__c = resourceMap.get(cs.Project_Resource__c).Candiadate_user__c;               
                   }              
              }
         }
        
    }     
    if (trigger.isBefore && trigger.isInsert) {
        List<Id> resourceIds = new List<Id>();
         //Populate a list of all related cases
         for(Candidate_Task__c cs : trigger.new)
         {
              resourceIds.add(cs.Project_Resource__c);
         }        
         if(resourceIds.size()>0)
         {    
          //Query those resurces
              List<Project_Resource__c> resources = [Select Id, Candiadate_user__c from Project_Resource__c where Id in: resourceIds];                                                         
             //Create a map
              Map<Id,Project_Resource__c> resourceMap = new Map<Id,Project_Resource__c>(resources);
              //Update the Project_Resource__c objects
              for(Candidate_Task__c cs : trigger.new) {
                   //Only process if there's a case mapped
                   if(resourceMap.containsKey(cs.Project_Resource__c)) {
                        //Set the values
                        cs.Employee__c = resourceMap.get(cs.Project_Resource__c).Candiadate_user__c;               
                   }              
              }
         }       
        
    } 
               
}



2. HoursNoDeleteonCandidateTask


/*
 Raj Vooturi - display error for delete on Task
     
*/
trigger HoursNoDeleteonCandidateTask on Candidate_Task__c (before delete) {
    for (Candidate_Task__c a : Trigger.old) {
        if(trigger.isdelete) {
            if ( (a.Resource_incurred_hours__c>0) || (a.Resource_Incurred_Expense__c>0) ) {
                a.addError('You can\'t delete this Task Resource Record. This Task Resource has time and expense records that are submitted by resources');
            }
        }    
    }    
}


Thanks,
