MSS Perf Mgmt Error

Question

Testing the ECC 6 EHP4 WD for ABAP services hap* for the MSS performance mgmt iViews in the Portal.  Unfortunately, an ABAP runtime error occurs.  The services are activated...any ideas?
Runtime Errors         OBJECTS_OBJREF_NOT_ASSIGNED_NO
Exception              CX_SY_REF_IS_INITIAL
Date and Time          08/24/2010 09:27:49
Short text
     Access via 'NULL' object reference not possible.
What happened?
     Error in the ABAP Application Program
     The current ABAP program "/1BCWDY/FQAYVDRAIPMJEC16CE0U==CP" had to be
      terminated because it has
     come across a statement that unfortunately cannot be executed.
Error analysis
    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 "PREPARE_NAVIGATION" "(METHOD)", nor was it propagated by a RAISIN
     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.

Answer 1

Hello,
have a search for messages which refer to "CL_HRHAP00_STARTPG_POWL"
this issue is fairly common. It is caused by missing data/configuration for the performance process.
You can place a breakpoint in the various method of the POWL feeder class CL_HRHAP00_STARTPG_POWL (which is what you application is calling) and you will see that it is within this that the error is generated, and hopefully will be able to see what data/configuration you need to maintain to stop it from happening!
Good luck,
Chris
