Error while Creation on Track(create/save) CBS authorization exception

Hi All,

I am trying to create Track in CMS in NWDI. When I am saving after importing relevant SC (ESS/MSS),

I got below error while saving.

CBS (URL http://sapdevep:50000/tc.CBS.Appl/archiveapi2/) authorization exception: User not authorized to log into build server. ( Service call exception; nested exception is: com.sap.engine.services.webservices.jaxrpc.exceptions.InvalidResponseCodeException: Invalid Response Code: (401) Unauthorized. The requested URL was:"http://sapdevep:50000/CBSWebService/CBSHttpSOAP?style=rpc" )

request you guide me for this problem.

Thanks,
