Hi Pranil,

Greetings to you!

You can use the below trigger: 
trigger TrimAccName on Account (before insert, before update) {

    for( Account acc : Trigger.new){
        String accName = acc.Name;
        acc.Name = accName.substring(0,accName.length()-3);
    }
}

I hope it helps you.

Kindly let me know if it helps you and close your query by marking it as solved so that it can help others in the future. It will help to keep this community clean.

Thanks and Regards,

Hi,

Try below:
  
String s = 'MyAccount';
system.debug(s.substring(s.length()-3,s.length()));

Hi Pranil,

You can use the below code.

I have written a trigger as per your requirement.  

---Trigger --- 
trigger AccountDeletion on Account (before insert, before update) {
    if(  trigger.isBefore && (trigger.isInsert || trigger.isUpdate )){ 
        DeleteLast_ThreeDigits.deleteAccountLastThreeDigits(trigger.new);
    }
}
---Apex Class--- 
public class DeleteLast_ThreeDigits {
    
    public static void deleteAccountLastThreeDigits(List<Account> accountList){
        try{
            for( Account acc : accountList){
                if(acc.Name.length() >3){
                String accName = acc.Name;
                acc.Name = accName.substring(0,accName.length()-3);
                }
            }
        }catch(Exception exp){
            System.debug('Exception Cause-->>'+exp.getMessage()+'Line Number-->>'+exp.getLineNumber());
        }
    }
}

I hope you find the above solution helpful. If it does, please mark as Best Answer to help others too.
