Sorry, since i am new to this, i might not be able to explain it with right term. If you could see the attached picture, you could understand what i meant by edit scenario.

when you click New button it's an insert and when you open the record it's the existing record

you can differentiate this using onLoad client script and use g_form.isNewRecord() function

This will help you determine if it's a new record or an existing record

function onLoad(){
	if(!g_form.isNewRecord())
		g_form.setReadOnly('fieldName', true);
}

If my response helped please mark it correct and close the thread so that it benefits future readers.
