ValueMappingReplication, authentication problem

Hi all,

Still trying to get valuemappingreplication going. I'm getting the following error from the NWA logs, and 401 unauthorized in the monitor.

Clearly there's an auths problem, but for which user ?? None of the usual suspects are locked, especially PIISUSER which is the HTTP RFC user.

Any clues for me ????

Thanks in advance, Guy

    I believe ValueMappingReplication is all on the Java stack.

    Something to check: Does the user you are using to log into PI to perform the valuemappingreplication have role SAP_XI_APPL_SERV_USER?

    Hi ,

    Please check the follwing

    1) If the JAVA inbound proxies are activated or not

    2) Try with PIAPPL user role.

    • Thanks for any help Ajay,

      Yes, I've registered the proxy and I'm using PIAPPLUSER. At least, I THINK I am....maybe that's the point....what does the ERP system use to communicate with the service repository? I'm assuming that it uses SAP_PROXY_ESR..perhaps that's where I'm going wrong.

    HA !!!

    Finally solved it myself; the authentication in the receiving channel needs to be 'Use logon data for NON-SAP system'
