Hi Ramzy,

Please browse through chrome or sdn , there is a lot of documents and discussions, any how find the below URL, which might be helpful.

Create a Function Module and full the below Code :

Sample code :

DATA: http_client TYPE REF TO if_http_client,

      host_str TYPE string VALUE 'www.myservice.in',

      service_str TYPE string,

      path TYPE string VALUE  'my path',

      errortext TYPE string. "used for error handling

DATA  : wf_string1 TYPE string,

         lw_inputs TYPE string,

         error_text type string,

         subrc TYPE SY-SUBRC,

         lw_outputs TYPE  string.

CALL METHOD cl_http_client=>create_by_url

  EXPORTING

    url                = 'myurl'

  IMPORTING

    client             = http_client

  EXCEPTIONS

    argument_not_found = 1

    plugin_not_active  = 2

    internal_error     = 3

    OTHERS             = 4.

  IF sy-subrc <> 0.

*  MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno

*             WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.

ENDIF.

CALL METHOD http_client->request->set_header_field

  EXPORTING

    name  = '~request_method'

    value = 'POST'.

CALL METHOD http_client->request->set_header_field

  EXPORTING

    name  = '~server_protocol'

    value = 'HTTP/1.1'.

CALL METHOD http_client->request->set_header_field

  EXPORTING

    name  = '~request_uri'

    value = 'mypath'.

CALL METHOD http_client->request->set_header_field

  EXPORTING

    name  = 'Content-Type'

    value = 'application/soap+xml; charset=utf-8'."'text/xml; charset=utf-8'.

CALL METHOD http_client->request->set_header_field

  EXPORTING

    name  = 'Content-Length'

    value = '19000'."txlen.

CALL METHOD http_client->request->set_header_field

  EXPORTING

    name  = 'SOAPAction'

    value = 'myURL'.

concatenate 'data u need sned' into wf_string

CALL METHOD http_client->request->set_cdata

  EXPORTING

    data   = wf_string1

    offset = 0

    length = '19000'.
