hi rohit,

it looks like that your webservice is not authenticated correctly.

did you provide the logon credentials for the webservice (single service administration)?

if you call the wsdl directly - can you access it with the logon credentials of your (or technical) user?

regards,

christian

Hi Christian,
  Yes , already provided the logon credential in Single Service Administrator as
   SOA - Application and senario communication - Single Service Administrator - Consumer proxies
    then in  ServicesRegistrySi i provided the HTTp Authentication with userId/Password

and i checked from wsnavigator with same credential BPM web service is working fine and process triggered for the same

Please tell if somthing is wrong.

Hi christian,
I have already read this thread and i did the chenges accordingly still gettin gthe same error
not able to get any idea

[christian_santej]

hi rohit,

did you restart the server - maybe it's some sort of a caching issue?

have you tried to turn on the webservice logging & tracing (nwa - SOA - Logs and Traces)?

if this doesn't help then i'm out of ideas - sorry.

regards,

christian

that configuration is not that relevant.

when you  import the wsdl, did u create the service group? you have to assign provider system for the group.

the user who is calling the ws from web dynpro should be assigned with role "sap_bpm_trigger_event" if your bpm is 7.2sp4+

Hi Jun,
thanks for your reply , i am usinf 7.3 SP11 version and assigned the "sap_bpm_trigger_event" for the user who is triggering the BPM from Web Dynpro , still getting the Authentication Errior

and i am not getting where i need to create service gruup and have to assignrd the provider system to that service group , can u explain in detail.

thanks,

Rohit
