Create a  Opportunity Contact role between the Converted Contact and Opportunity. The role value should be fetched from "Contact Role" field.

Can anyone help me how to write trigger on this.

Is there any way where  I want to display  only closed date and month format in the reports for Opportunity Object using Formula  or any way.

Hey all,

I have created the following Apex trigger that will create, update and delete Opportunity Contact Roles based on a Contact Lookup field placed on the Opportunity. Everything works great currently. I am just trying to figure out one final scenario. If John Doe already has a Contact Role but is not the Primary Contact Role and I want him to be. I want to be able to change my look up field to him and then have that check him as the primary. Currently it just creates a new one and checks them both as primary. So what I need to do is check the current Contact Roles and if there is already one with the same name as in the Lookup field then just check that one as primary, but if there isn't then create a new one. Below is the code. Please let me know if you need further description.

Thanks,
 

trigger CreateContactRole on Opportunity (after insert, after update) {
    
    List<OpportunityContactRole> newContactRoleList = new List<OpportunityContactRole>();
    List<OpportunityContactRole> oldContactRoleList = new List<OpportunityContactRole>();
    Set<Id> OppId = new Set<Id>();
    sET<Id> ContactId = new Set<Id>();
    
    if(Trigger.isInsert) {
        for(Opportunity opp : Trigger.new) {
          if(opp.Primary_Contact__c != null) {
              //Creating new Contact Role
              newContactRoleList.add(new OpportunityContactRole(ContactId=opp.Primary_Contact__c,OpportunityId=opp.Id,Role='Decision Maker',IsPrimary=true));
          }
      }
    }
    
    if(Trigger.isUpdate) {      
      for(Opportunity opp : Trigger.new) {
          if(opp.Primary_Contact__c != null && Trigger.oldMap.get(opp.Id).Primary_Contact__c == null) {

              newContactRoleList.add(new OpportunityContactRole(ContactId=opp.Primary_Contact__c,OpportunityId=opp.Id,Role='Decision Maker',IsPrimary=true));
          }
            else if(opp.Primary_Contact__c != null && Trigger.oldMap.get(opp.Id).Primary_Contact__c != null) {
