Hi Bharath,

In your code, acc is a List<Account>. So you cannot directly access Name field from acc. Instead either you can use

acc[0].Name.addError('you cannot create the duplicate account');

OR

For(Account a : acc)

{

a.NAME.addError('you cannot create the duplicate account');

}

Thanking you,

Arun
