  Error analysis
      An exception has occurred which is explained in more detail below. The
      exception is assigned to class 'CX_SY_REF_IS_INITIAL' and was not caught in
       procedure
      "HANDLEDEFAULT" "(METHOD)", nor was it propagated by a RAISING clause.
      Since the caller of the procedure could not have anticipated this
      exception, the current program was terminated.
      The reason for the exception is:
      You are trying to access a component with a 'ZERO' object reference
      (points to 'nothing').
      An object reference must point to an object (an instance of a class)
      before it can be used to access a component. The reference has either
      never been set, or it was set to 'ZERO' with a CLEAR statement.
