Hi All,

I am trying to update the owners of contact records to owner of parent account record. But for records where contact owner is inactive I am unable to change its owner. I have written a batch class but it does not work. Could anyone let me know whats the issue?(I have all the required permission to update the inactive owner records)

Here is my code:

global class BatchUpdateCon implements Database.Batchable<sObject>
       {      
            
            global Database.QueryLocator start(Database.BatchableContext BC)
            {
               String query = 'Select Id, owner.Isactive, OwnerId, Account.OwnerId from Contact where owner.isactive = False';
               return Database.getQueryLocator(query);
            }

            global void execute(Database.BatchableContext BC,List<Contact> scope)
            {
                  List <Contact> contactToUpdate = new list<Contact>();
                  Set<Id> accIds = new Set<Id>();
                  for(Contact con : scope)
                  {
                       accIds.add(con.AccountId);
                  }
                  
                  Map<Id, Account> mapAccount = new Map<Id, Account>([select id, ownerId from Account where id in:accIds]);
                  for(Contact con : scope)
                  {
                        if(con.AccountId != null && con.OwnerId != mapAccount.get(con.AccountId).OwnerId)
                        {
                            System.debug('Inside--->'+con.Accountid);
                            con.OwnerId = mapAccount.get(con.AccountId).OwnerId; 
                            contactToUpdate.add(con);  
                        }
                  }
                  update contactToUpdate;
            }

            global void finish(Database.BatchableContext BC)
            {
            }
       }
