Hi Jun,
The default trace file is showing:
Could not save user mapping data for principal ''USER.PRIVATE_DATASOURCE.un:user_admin'' and system ''EnterprisePortal:SAP_BW'' because the credentials could not be verified against the backend system. Most likely the credentials are invalid. If you are sure that the credentials are ok, please check SAP note 792850.
