I have a requirement where I have to update the status of the Service Request. In the implementation class of the view, I am trying to do that by updating the attribute ACT_STATUS of the BtStatus for a Service Request. But here the Set_Property( ) method is not updating the value. I checked using the method 'is_property_readonly which return 'X' i.e the property for that attribute is Read Only. The method 'is_changeable( )' also returns false. What would be the correct approach to achieve that.
