KEFC - Unicode error whlie loading external COPA data?

Hello everyone,

I am using transaction KEFC (program RKEVEXT3) to load a flat text file into CO-PA. Our team has defined a custom structure ZCOPAEXT to load this information.

However, when KEFC is executed, the program fails with a message "The file cannot be imported in this format."

Debugging the program shows that this error occures in subroutine CHECK_UNICODE in include RKCDFILEINCFOR. I've provided the code of below.

FORM check_unicode USING value(repid) TYPE kcdu_repid.
  DATA: subrc LIKE sy-subrc,
        l_it242s LIKE cfsend_tab OCCURS 100 WITH HEADER LINE,
        l_charlen TYPE i,
        l_char TYPE c LENGTH 1.

  CALL FUNCTION 'KCD_SENDERSTRUC_LOGICAL_READ'
    EXPORTING
      repid  = repid
    TABLES
      e_send = l_it242s
    EXCEPTIONS
      OTHERS = 0.

  DESCRIBE FIELD l_char LENGTH l_charlen IN BYTE MODE.
  LOOP AT l_it242s WHERE ftype CA 'IFPX'.
    EXIT.
  ENDLOOP.
  IF sy-subrc = 0 AND l_charlen <> 1.
    subrc = 4.
    EXPORT subrc TO MEMORY ID 'KCDFILE0'.

* Die Datei kann in diesem Format nicht eingelesen werden
    CALL FUNCTION 'KCD_MESSAGES_COLLECT'
      EXPORTING
        repid = repid
        grpid = grpid
        msgty = 'A'
        arbgb = 'DU'
        msgnr = '027'.
    MESSAGE a027(du).
  ENDIF.
ENDFORM.                    "no_floats_and_integers

The error seems to occur with the "DESCRIBE FIELD" statement. The field length in bytes of the 1 character field "l_char" is always 2. This triggers the IF statement where "l_charlen <> 1".

I've searched the OSS notes and this forum, but it doesn't seem like anyone has experienced a similar issue. Any ideas on how to resolve this? I would like to avoid having to copy the program (and includes) and create a custom solution.

Thanks very much for any input you can provide.
