How to call procedure RMSSUB_RECEIVING.CONSUME

 Hi All,Can anyone please guide me as to how I may call the following procedure of RIB?

PROCEDURE CONSUME(O_status_code          IN OUT  VARCHAR2,

                  O_error_message        IN OUT  VARCHAR2,

                  I_message              IN      RIB_OBJECT,

                  I_message_type         IN      VARCHAR2,

                  O_rib_otbdesc_rec         OUT  RIB_OBJECT,

                  O_rib_error_tbl           OUT  RIB_ERROR_TBL)

Here is how I am trying to call this procedure in PL/SQL:-

DECLARE

o_status_code   varchar2(10);

o_error_message varchar2(255);

o_rib_otbdesc_rec rib_object;

o_rib_error_tbl rib_object;

--O_rib_otbdesc_rec RIB_OBJECT,

--O_rib_error_tbl RIB_ERROR_TBL,
