I am new in Microsoft Dynamics 365 I want to add Validation write method which allow my name not to be duplicated.
Can anyone help me out in this method.
Could you please give us more details. For example, if you want to make sure that a field value isn't duplicated in a table, why don't you simply use a unique index?
And as I told you in your previous thread, make sure that you use a descriptive thread title ("Microsoft Dynamics D365" says nothing about the actual topic) and ask questions about D365FO in a D365FO forum. Let me rename this thread too for you...
thanks
