Error raise OPERATION_NO_AUTHORIZATION. in FM SO_OBJECT_SEND

Hi Experts,

Any idea why the FM is raising an exception OPERATION_NO_AUTHORIZATION.

I have coded :

CALL FUNCTION 'SO_OBJECT_SEND'

EXPORTING

FOLDER_ID = FOLDER_ID

• FORWARDER = ' '

• OBJECT_FL_CHANGE =

• OBJECT_HD_CHANGE = ' '

OBJECT_ID = object_id

• OBJECT_TYPE = ' '

OUTBOX_FLAG = 'X'

OWNER = sy-uname

• STORE_FLAG = ' '

• DELETE_FLAG = ' '

• SENDER = ' '

• CHECK_SEND_AUTHORITY = 'X'

• CHECK_ALREADY_SENT = ' '

• GIVE_OBJECT_BACK =

ORIGINATOR = ''

ORIGINATOR_TYPE = 'J'

LINK_FOLDER_ID = link_folder_id

• SEND_REQUEST_OID = ' '

• IP_ENCRYPT = 'U'

• IP_SIGN = 'U'

• IP_REC_COUNT_ADD =

• IMPORTING

• OBJECT_ID_NEW =

• SENT_TO_ALL =

• ALL_BINDING_DONE =

• OFFICE_OBJECT_KEY =

• ORIGINATOR_ID =

• E_SEND_REQUEST_OID =

TABLES

• OBJCONT =

• OBJHEAD =

• OBJPARA =

• OBJPARB =

RECEIVERS = it_RECEIVERS

• PACKING_LIST =

• ATT_CONT =

• ATT_HEAD =

• NOTE_TEXT =

• LINK_LIST =

• APPLICATION_OBJECT =

• EXCEPTIONS

• ACTIVE_USER_NOT_EXIST = 1

• COMMUNICATION_FAILURE = 2

• COMPONENT_NOT_AVAILABLE = 3

• FOLDER_NOT_EXIST = 4

• FOLDER_NO_AUTHORIZATION = 5

• FORWARDER_NOT_EXIST = 6

• NOTE_NOT_EXIST = 7

• OBJECT_NOT_EXIST = 8

• OBJECT_NOT_SENT = 9

• OBJECT_NO_AUTHORIZATION = 10

• OBJECT_TYPE_NOT_EXIST = 11

• OPERATION_NO_AUTHORIZATION = 12

• OWNER_NOT_EXIST = 13

• PARAMETER_ERROR = 14

• SUBSTITUTE_NOT_ACTIVE = 15

• SUBSTITUTE_NOT_DEFINED = 16

• SYSTEM_FAILURE = 17

• TOO_MUCH_RECEIVERS = 18

• USER_NOT_EXIST = 19

• ORIGINATOR_NOT_EXIST = 20

• X_ERROR = 21

• OTHERS = 22

.

IF sy-subrc <> 0.

• MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

• WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.
