Error when consuming Web Service in SAP R/3 ECC 6.0

Question

Hi to everyone.
I have created an asynchronous Web Service in SAP R3, which I want to use in SAP PI later.
When I test the Web Service using WS Navigator or XMLSpy the following error occurs:
SOAP Runtime Protocol: ABAP Runtime exception: 1F09B73915F6B645E10000000A11447B occurred in program CL_SOAP_APPLICATION_PROXY=====CP CP in include CL_SOAP APPLICATIONPROXY=====CM008 at position 110
SOAP Runtime Protocol: Exception message: An exception with the type CX_SY_REF_IS_INITIAL occurred, but was neither handled locally, nor declared in a RAISING clause
I tested another synchronous Web Service developed by me in the same system, and the error does not occurs.
I just searched an OSS Note and does not find anything.
There are some restrictions in Web Service type developed in SAP R/3?
Thanks in advance.

Hi.
I think I must clarify my question.
The Web Service is not called inside SAP R/3 but externally. For testing pourpose I actually use WS Navigator and XMLSpy.
The method inside ABAP Server Proxy which is exposed as a Web Server in SAP R/3 system is the following. Note that the Web Service is Asynchronous.
METHOD zpi_ii_test_ws_4_in~test_ws_4_in.
  DATA: lwa_zpi_test TYPE zpi_test.
  lwa_zpi_test-mandt = input-mt_test-record-client.
  lwa_zpi_test-bukrs = input-mt_test-record-company.
  lwa_zpi_test-belnr = input-mt_test-record-document.
  lwa_zpi_test-gjahr = input-mt_test-record-year.
  INSERT zpi_test FROM lwa_zpi_test.
  COMMIT WORK.
ENDMETHOD.

  SELECT MAX( belnr ) INTO l_belnr
    FROM zpi_test
    WHERE bukrs EQ l_bukrs
      AND belnr IN lr_belnr
      AND gjahr EQ l_gjahr.
  IF l_belnr IS INITIAL.
    l_belnr = '4700000000'.
  ELSE.
    l_belnr = l_belnr + 1.
  ENDIF.
  lwa_zpi_test-mandt = sy-mandt.
  lwa_zpi_test-bukrs = l_bukrs.
  lwa_zpi_test-belnr = l_belnr.
  lwa_zpi_test-gjahr = l_gjahr.
  INSERT zpi_test FROM lwa_zpi_test.
  COMMIT WORK.
  output-mt_resp-msg = l_belnr.
ENDMETHOD.
I hope to have clarified my question.
