How to read response from WebService call

Question

Hi,
I am consuming webservices in ABAP. I got proxy classes created. Port is also created.
I am calling classes generated by proxy in ABAP. Classes creates few structure by system. when i make a call to service, I am not getting importing values in veariables declared. Trace file (in SOAMANAGER ) shows call successful & XML file shows the correct response values, but are not appearing in program variables. I declared variables of same type generated by system.
My question is, am I missing any step.configuration? or how to read the variables?
Thanks in advance.

You coud create a procedure like this:
CREATE OR REPLACE PROCEDURE soap_env_pr (p_soap_env IN VARCHAR2)
IS
   v_start     NUMBER;
   v_end       NUMBER;
   v_message   VARCHAR2 (400);
   v_length    NUMBER;
BEGIN
   v_start := INSTR (p_soap_env, '<ns0:Ok>');
   v_length := LENGTH ('<ns0:Ok>');
   v_end := INSTR (p_soap_env, '</ns0:Ok>');
   v_message :=
          SUBSTR (p_soap_env, v_start + v_length, v_end - v_start - v_length);
   HTP.prn ('Ok: ' || v_message);
   v_start := INSTR (p_soap_env, '<ns0:SessionNumber>');
   v_length := LENGTH ('<ns0:SessionNumber>');
   v_end := INSTR (p_soap_env, '</ns0:SessionNumber>');
   v_message :=
          SUBSTR (p_soap_env, v_start + v_length, v_end - v_start - v_length);
   HTP.prn ('SessionNumber: ' || v_message);
   v_start := INSTR (p_soap_env, '<ns0:ErrorMessage>');
   v_length := LENGTH ('v_length');
   v_end := INSTR (p_soap_env, '</ns0:ErrorMessage/>');
   v_message :=
          SUBSTR (p_soap_env, v_start + v_length, v_end - v_start - v_length);
   HTP.prn ('ErrorMessage: ' || v_message);
END;and call it like this:
BEGIN
   soap_env_pr
      ('<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"><env:Header/>
<env:Body>
* <invokeScenarioResponse xmlns:ns0="xmlns.oracle.com/odi/OdiInvoke/" xmlns="xmlns.oracle.com/odi/OdiInvoke/">*
* <ns0:Ok>true</ns0:Ok>*
* <ns0:SessionNumber>2223201</ns0:SessionNumber>*
* <ns0:ErrorMessage/>*
* </invokeScenarioResponse>*
</env:Body>
</env:Envelope>'
END;That would give you this output:
Ok: true
SessionNumber: 2223201
