Runtimr error OBJECTS_OBJREF_NOT_ASSIGNED when i schedule pgm in back grd

Question

Hi All
when I schedule any BDC pgm in Background by giving job name in SM36 .
It is giving an runtimr error OBJECTS_OBJREF_NOT_ASSIGNED and Exception CX_SY_REF_IS_INITIAL .
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 "C14T_LISTTOOL_CALL_ALV_GRID" "(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 (variable: "GRID1").
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.
But it is working fine when i running with options 'N' & 'A' in call transaction. when i execute I'm searching for sap note but not able to find it,
If any one can solve this issue please ...

Play suji,
In EHS there is one transaction called CVD1, this program closes rejected report shippings thru call transaction previously this program was working fine with 4.7 version recently sap version upgrade has taken place recent version is ECC6.0, the error is occuring in standard program while calling the call transaction for tcode CVD1.
