  Runtime Errors         MOVE_CAST_ERROR
  Except.                CX_SY_MOVE_CAST_ERROR
  ABAP Program           SAPLSTXB
  
  An exception has occurred which is explained in more detail below. The
  exception is assigned to class 'CX_SY_MOVE_CAST_ERROR' and was not caught in
   procedure
  "CREATE_CODING_FOR_NODE" "(FORM)", 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:
  During the 'CAST' operation ('?=' or 'MOVE TO') an attempt was made to
  assign a reference to a reference variable.
  The current content of the source variable is not compatible with the
  target variable however.
  Source type: \CLASS=CL_SSF_FB_SECTION
  Target type: "\CLASS=CL_SSF_FB_EVENT"
