Iview cannot be previewed after ESS BP deployment

Question

Dear Experts,
Kindly need your help.
Our iview (namely personal data iview in ESS) show blank (I mean really blank) iview in preview mode(portal content directory and as content administrator). We previously deployed a downloaded ESS Business Package, to get this iview.
This occurs the same for all new iviews (deployed iviews according to ESS BP), but the "Overview" iview.
When I preview the Overview iview, it shows error:
The initial exception that caused the request to fail, was:
   com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Failed to resolve JCO destination name 'SAP_R3_SelfServiceGenerics_MetaData' in the SLD. No such JCO destination is defined in the SLD.

We have maintained the jco connection properly though.
But when we logged in as user, the iview works fine.
Any idea how to manage this?
Thank you.

Hi,
So the JCO connection is green? Yes, all JCOs connection are all green
The user used for usermapping is the same as for the other JCO metadata connection? Yes
The mapped user is a SAP service user? we are using SAPJSF userID with profile SAP_ALL and SAP_NEW.
Actually, all JCOs connection even SAP_R3_SelfGeneric_metada have been tested and pinged successfully.
Thank you.
