Hi Shyam,
Please check the genil class name in spro->genric intraction layer.
check the class name and then check the method if_genil_appl_intly~get_objects().
an d change the lr_ attr_props->set_property_by_name(iv_name =
iv_value = if_genil_obj_attr_prperties=>read_only/changable.)
you can change here.
Thanks and Reagrds
