SAP calling thrid party WebService issue

[Former Member]

Hi All,

I am seeing the below issue when I am trying to consume third party web service in sap. Tried different options and gone through lot of threads but I am still not able to get solution. I really need some input and help here to move little further.

1. I have created consumer proxy

2. Create logical port 'ABC' - the authentication method is http, userid/password, as part of the logical port creation I have proved the user/password details. Since I already provided in SOAMANAGER as part logical port configurations, I am not explicitly passing those credentials in my ABAP code as WS_HEADER protocol.

3. Program to execute the web service and provide input and expected to see success.

The below is the error I am facing.

Class Name: CL_SOAP_RUNTIME_CLIENT

SOAP Fault Exception caught: : Server was unable to
process request. ---> The type PageUp.WebService.PageUpPeople could not be
initialized. Unable to determine the correct instance ID for this service call!
---> Unable to determine the correct instance ID for this service
call!

The below is the code i am using:

DATA: client_proxy TYPE REF TO ZTEST_SOAP,
input TYPE ZGET_REVIEW_SOAP,
output TYPE ZGET_REVIEW_SOAP1,
oref TYPE REF TO cx_root,
text TYPE string.

DATA: ixml TYPE REF TO if_ixml,
xml_document TYPE REF TO if_ixml_document,
xml_root TYPE REF TO if_ixml_element,
xml_element TYPE REF TO if_ixml_element,
xml_node TYPE REF TO if_ixml_node.

DATA l_xstring TYPE xstring.
DATA l_string TYPE string.
DATA: lr_header_protocol TYPE REF TO if_wsprotocol_ws_header.
DATA: interface TYPE REF TO ZTEST_SOAP.
DATA: name TYPE string,
namespace TYPE string.

TRY.
    CREATE OBJECT client_proxy
      EXPORTING
        logical_port_name = 'ABC'.
  CATCH cx_ai_system_fault INTO oref.
    text = oref->get_text( ).
ENDTRY.
IF NOT text IS INITIAL.
  WRITE / text.
ENDIF.

*convert to xstring
l_xstring = cl_proxy_service=>cstring2xstring( l_string ).
IF l_string IS NOT INITIAL.
*create ixml dom document from xml xstring
CALL FUNCTION 'SDIXML_XML_TO_DOM'
EXPORTING
   xml = l_xstring
   IMPORTING
   document = xml_document
   EXCEPTIONS
   invalid_input = 1
   OTHERS = 2.
IF sy-subrc = 0 AND xml_document IS NOT INITIAL.
    xml_root = xml_document->get_root_element( ).
    xml_element ?= xml_root->get_first_child( ).
*add header element by element to soap header
     WHILE xml_element IS NOT INITIAL.
    name = xml_element->get_name( ).
    namespace = xml_element->get_namespace_uri( ).
    lr_header_protocol->set_request_header( name = name namespace = namespace dom = xml_element ).
    xml_element ?= xml_element->get_next( ).
  ENDWHILE.
ENDIF.
ENDIF.

*Fill request with to be retrieved
input-OFFER_STATUS = 'Made'.
input-filter-USER_EMAIL = 'test.ws@xxxxxxx.org'.
TRY.
CALL METHOD client_proxy->GET_REVIEW
    EXPORTING
      input  = input
    IMPORTING
      output = output.
   CATCH cx_ai_system_fault INTO oref.
    text = oref->get_text( ).
  CATCH cx_ai_application_fault INTO oref.
    text = oref->get_text( ).
  ENDTRY.

IF NOT text IS INITIAL.
  WRITE / text.
ELSE.
  WRITE 'Success'.
ENDIF.

Attached are the my logical port settings:

I just slightly modified the host names due to security reasons.

I highly appreciate your time in reviewing my question and helping me out here.

update....

if I add the below code it is working fine but due to security reason , client doesn't want to maintain the user/password in ABAP code.

I maintained user/password in SOAMANGER while selecting the userid/password authentication radio box  field. Then if I comment out below code, where I am seeing this error:

****************************************

get WS_HEADER protocol

    lr_header_protocol ?= client_proxy->get_protocol( if_wsprotocol=>ws_header ).

CONCATENATE

'<Header>'
'<AuthHeader xmlns="http://webservices.reviewtest.com.au/Value/ValueTestsome/">'
'<sUserName>testuser</sUserName>'
'<sPassword>testpwdddd</sPassword>'
'</AuthHeader>'
'</Header>'
INTO l_string.

Error:

Class Name: CL_SOAP_RUNTIME_CLIENT

SOAP Fault Exception caught: : Server was unable to
process request. ---> The type PageUp.WebService.PageUpPeople could not be
initialized. Unable to determine the correct instance ID for this service call!
---> Unable to determine the correct instance ID for this service
call!

The question is, why Web service is not accepting the user/password from soamanger configuration , where as if I pass hard coded  from the ABAP code using WS_HEader protocol it works fine but we do not want to pass user/password from ABAP code .

is any one experienced this kind of behavior?

Still going through lots of threads but not getting much help.

Created high sap note but still nothing heard yet.

The question is, why this WebService works  when I pass the AuthHeader as part of the soap message. but we do not want to keep the usr/password in abap code.

If I comment out the below code , it throws an error.

********************************************

* get WS_HEADER protocol

    lr_header_protocol ?= client_proxy->get_protocol( if_wsprotocol=>ws_header ).
CONCATENATE
'<Header>'
'<AuthHeader xmlns="http://webservices.test.com.ie/values/ValueOneService/">'
'<sUserName>test</sUserName>'
'<sPassword>test</sPassword>'
'</AuthHeader>'
'</Header>'
INTO l_string.

Thanks
