ABAP proxy web service authentication

Question

Hi,
We are trying to develop an ABAP proxy for a web service call on ECC6 (SP14).
The web service (provided by another SAP system) uses basic authentication. The proxy has been created as has the logical endpoint/service (via SOAMANAGER). In the endpoint I have provided the credentials for authentication.
Manually testing the proxy via SE80 works fine.
When I try and call the proxy via a program it prompts for user id/password. If provided the call works.
DATA: ZPROXY   type REF TO ZMY_PROXY,
          INPUT       type ZMY_PROXY_REQUEST,
          OUTPUT    type ZMY_PROXY_RESPONSE.
  TRY.
     CREATE OBJECT ZPROXY.
     CATCH CX_AI_SYSTEM_FAULT.
  ENDTRY.
  TRY.
     CALL METHOD ZPROXY->LIST_USERS
       EXPORTING
         INPUT  = INPUT
       IMPORTING
         OUTPUT = OUTPUT.
     CATCH CX_AI_SYSTEM_FAULT .
     CATCH CX_AI_APPLICATION_FAULT .
  ENDTRY.
My expectation is that the proxy would derive the credentials from the logical endpoint.
Am I missing something?
Thanks in advance.

Hi Olivier,
Yes - the consumer system is ABAP Netweaver 7.0.
It has SP14. The webservice provider system is running at the same level.
The webservice provider was created using the wizard to convert an RFC enabled function module. I then used SOAMANAGER to created the provider endpoint. On the consumer side it was the same - wizard to create the proxy & then SOAMANAGER for the endpoint.
I checked the services on the provider system & the service indicated was activated already - which was expected as the web service call itself works fine.

Any other suggestions?
Thanks again,
