applcation ess~in~claims picking the R/3 url in place of Portal

hi Team,

I am getting the below error message when click on the UWL work item in manager inbox

URL http:// :8000/webdynpro/dispatcher/ sap.com/ess~in~claims/ClaimAdvanceApproval_IN call was terminated because the corresponding service is not available.

Actually this is the java application and picking the R/3 host details? please let me know where to correct these settings.

All other item in manger are working fine...only problem with the item type "claims and advance approval" type.

please suggest me the needful.

Regards,

Narpal Singh
