Mutually convertible Unicode

Question

When I change the next code (Adaptation unicode):
IF t004-sakln > 0.
*{   REPLACE        &$&$&$&$                                          1
*      DESCRIBE FIELD ska1-bilkt LENGTH sy-fdpos.
      DESCRIBE FIELD ska1-bilkt LENGTH sy-fdpos IN CHARACTER MODE.
I obtain the next error sintaxis:
Can you help me, please?
"SKC1A-GSBER" and "X_FF_GSBER" are not mutually convertible in a Unicode program . . . . .
IF NOT ( repwaers IS INITIAL ).
    ctyp_waers  = repwaers.
  ELSE.
    ctyp_waers  = skc1a-hwaer.
  ENDIF.
  IF fi_lc_ex = '2'.
*   Extrakt an FI_LC, Geschäftsbereich austauschen
    SELECT SINGLE * FROM tgsb WHERE gsber = skc1a-gsber.
*   IF SY-SUBRC = 0 AND TGSB-GSBER_KONS <> SPACE.           "vhs134295
    IF sy-subrc = 0.                                        "vhs134295
      skc1a-gsber = tgsb-gsber_kons.
    ELSE.
      IF NOT skc1a-gsber IS INITIAL.                        "vhs134295
*       Fehler, Gsber auf HexFF setzen
        skc1a-gsber = x_ff_gsber.
      ENDIF.                                                "vhs134295
    ENDIF.
  ENDIF.
Cordial greetings.

Hi,
under Unicode you can't easely assign values from one variable to another with different datatype.
skc1a-gsber is char4 and x_ff_gsber seams to be type x?
Under Unicode there are strict rules. Instead of x = y you can use field-symbols.
This coding may help you:
DATA: z_gsber    TYPE skc1a-gsber,
          x_ff_gsber TYPE x.
FIELD-SYMBOLS: <f_gsber>          TYPE skc1a-gsber,
               <f_ff_gsber>      TYPE x.
ASSIGN z_gsber TO <f_gsber>.
ASSIGN x_ff_gsber TO <f_ff_gsber>.
<f_gsber> = <f_ff_gsber>.
The variable z_gsber has now the same value as x_ff_gsber.
