Hello friend,

you can use function module SSFC_BASE64_DECODE / SSFC_BASE64_ENCODE to do decode & encode.

Best Regards,

Jerry

Hi,

use this code for solve your issue:

TRY.

           CALL METHOD zcl_fie_oioubl_import=>decode_base64
             EXPORTING
               iv_base64_string = lv_file_woh
               iv_output_string = 'X'
             IMPORTING
               ov_string        = lv_file_decode.
         ENDTRY.
       ELSE.
         lv_file_decode = lv_file_woh.
       ENDIF.

method: decode_base64(

CHECK iv_base64_string IS NOT INITIAL.

   CONSTANTS:
     lc_op_dec TYPE x VALUE 37.
   DATA:
     lr_conv TYPE REF TO cl_abap_conv_in_ce.

   CALL FUNCTION 'SSFC_BASE64_DECODE'
     EXPORTING
       b64data = iv_base64_string
     IMPORTING
       bindata = ov_xstring
     EXCEPTIONS
       SSF_KRN_ERROR                  = 1
       SSF_KRN_NOOP                   = 2
       SSF_KRN_NOMEMORY               = 3
       SSF_KRN_OPINV                  = 4
       SSF_KRN_INPUT_DATA_ERROR       = 5
       SSF_KRN_INVALID_PAR            = 6
       SSF_KRN_INVALID_PARLEN         = 7
       OTHERS                         = 8.

IF sy-subrc <> 0.
     RAISE EXCEPTION TYPE zcx_fie_oioubl_import
      EXPORTING sy_object = sy.
ENDIF.

IF iv_output_string = 'X'.
   TRY.
       lr_conv = cl_abap_conv_in_ce=>create( input = ov_xstring ).
       lr_conv->read( IMPORTING data = ov_string ).
   ENDTRY.
ENDIF.

)

       "create new file with correct filename
       OPEN DATASET lv_file_path FOR OUTPUT IN BINARY MODE.
       TRANSFER lv_file_decode TO lv_file_path . "FIXME: only if the filetype is binary
       CLOSE DATASET lv_file_path.
