  ----------------------------------------------------------------------------------------------------
  
  ----------------------------------------------------------------------------------------------------

  |Error analysis 
  | An exception has occurred which is explained in more detail below. The 
  | exception is assigned to class 'CX_SY_IMPORT_FORMAT_ERROR' and was not caught 
  | in procedure 
  | "LIST_GET_PROPERTIES" "(FUNCTION)", 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: 
  | When attempting to IMPORT the object "LIST_LINES", there was a format error. 
  | Unable to read an IMPORT dataset.
  | The dataset may have been processed using SQL and is 
  | thus no longer readable for the IMPORT. 
  ----------------------------------------------------------------------------------------------------
  
  

  ----------------------------------------------------------------------------------------------------
  |Information on where terminated 
  | The termination occurred in ABAP program "SAPLSLST", in "LIST_GET_PROPERTIES".
