Trigger to Copy the child field value to the parent object custom field.


In Account object we have a field called opportunity status and in opportunity object we have a field called 
Stage so when stage value will change the new value should display in the 
Account object field called opportunity status using trigger.

Hi Priya,

Greetings to you!

Please try the below code, I have tested in my org and it is working fine. Kindly modify the code as per your requirement.
  
trigger CopyOppToAccPicklist on Opportunity (after insert, after update) {
    
    List<Id> accIds = new List<Id>();
    List<Account> accounts = new List<Account>();
    
    for(Opportunity o : trigger.new){
        accIds.add(o.accountId);
    }
    
    for(Account a : [SELECT Id, Opportunity_Status__c FROM Account WHERE Id IN :accIds]){
        for(Opportunity opp:  trigger.new){
            a.Opportunity_Status__c=opp.StageName;
            accounts.add(a);
        }
    }
    if(accounts.size()>0){
        Update accounts;
    }
}

I hope it helps you.

Hello Priya,
Please find below code I have used Account and Contact you can change object according to yours and fields also.

trigger updateParentField on Contact (after update) {
    Map<ID,Account> contactMap = new Map<ID,Account>();
    Set<Id> accountIdSet = new Set<Id>();
    for(Contact con: trigger.new){
        accountIdSet.add(con.AccountId);
    }
    contactMap = new Map<ID,Account>([SELECT id,Description,(SELECT id,Description FROM Contacts) FROM Account WHERE ID IN:accountIdSet]);
    for(Contact con : trigger.new){
       Account myNewAccount = contactMap.get(con.AccountId);
       myNewAccount.Description = con.Description; 
    }
    update contactMap.values();
}
