ESS: "WDDynamicRFCExecuteException" received when previewign Address iView.

Question

Hi
We are starting to configure ESS portals on EP 7.0 to connect to ECC 6.0 system. While trying to check the connectivity from Portal to R/3 - SSO works fine.
However, the Address iView when displayed gives the following error;
The initial exception that caused the request to fail, was:
   com.sap.tc.webdynpro.modelimpl.dynamicrfc.WDDynamicRFCExecuteException: Access via NULL object reference not possible., error key: RFC_ERROR_SYSTEM_FAILURE

Here is the ST22 dump of the error on the ABAP system.
u201CRuntime Errors         OBJECTS_OBJREF_NOT_ASSIGNED_NO                              
Exception              CX_SY_REF_IS_INITIAL                                        
Date and Time          11/10/2008 15:32:46                                                                               
An exception occurred that is explained in detail below.                      
     The exception, which is assigned to class 'CX_SY_REF_IS_INITIAL', was not     
      caught in                                                                    
     procedure "HRXSS_PER_CLEANUP" "(FUNCTION)", nor was it propagated by a RAISING
      clause.                                                                      
     Since the caller of the procedure could not have anticipated that the         
     exception would occur, the current program is terminated.                     
     The reason for the exception is:                                              
     You attempted to use a 'NULL' object reference (points to 'nothing')          
     access a component.                                                           
     An object reference must point to an object (an instance of a class)          
     before it can be used to access components.                                   
     Either the reference was never set or it was set to 'NULL' using the          
     CLEAR statement.                                                                               
How to correct the error                                                          
     Probably the only way to eliminate the error is to correct the program.                                                                               
If the error occures in a non-modified SAP program, you may be able to        
     find an interim solution in an SAP Note.                                      
     If you have access to SAP Notes, carry out a search with the following        
     keywords:                                                                               
"OBJECTS_OBJREF_NOT_ASSIGNED_NO" "CX_SY_REF_IS_INITIAL"                       
     "SAPLHRXSS_PER_MAC" or "LHRXSS_PER_MACU04"                                    
     "HRXSS_PER_CLEANUP"   u201D
Has anyone else faced this error? Can you please suggest me a solution?
Thanks,

Answer 1

Hi Guys -
I found the resoution to this problem myself..
We had our ERP5COM @ SP 14 while all the other components ERP5ESS, ERP5MSS, etc were at a lower level ie SP 13.
So, by downgrading the above component we could Preview the iViews.
I am closing this post.
Thanks,
Raza.
