The OB SET NULL command stores the null value in the language object designated by the object parameter. object must have been defined using the C_OBJECT command or designate a 4D object field. In the property parameter, pass the label of the property where you want to store the null value. If the property already exists in object, its value is updated. If it does not exist, it is created.
