Open data set problem with binary mode

david_fryda2 — Tue, 28 Nov 2006 08:01:10 GMT

Hi everyone,

I am trying to read into a buffer the content of a binary file (like Excel) and to write that content file using open data set into a folder destination.

The file destination has a size diferent than from the original one and cannot be open.

Here is the code.


  DATA:  lv_file_name(100),
         lt_content LIKE sdokcntbin OCCURS 0 WITH HEADER LINE.

  MOVE '\computerTestA1.xls' TO lv_file_name.
  OPEN DATASET lv_file_name FOR INPUT IN BINARY MODE.
  IF sy-subrc NE 0.
    EXIT.
  ENDIF.

  DO.
    READ DATASET lv_file_name INTO lt_content-line.
    IF sy-subrc NE 0.
      EXIT.
    ENDIF.
    APPEND lt_content.
  ENDDO.
  CLOSE DATASET lv_file_name.
*  DELETE DATASET lv_file_name.

*****************************************************

  CLEAR: lv_file_name.
  MOVE '\computerTestB2.xls' TO lv_file_name.
  OPEN DATASET lv_file_name FOR OUTPUT IN BINARY MODE.
  IF sy-subrc NE 0.
    EXIT.
  ENDIF.

  LOOP AT lt_content.
    TRANSFER lt_content-line TO lv_file_name.
  ENDLOOP.
  CLOSE DATASET lv_file_name.

THanks in advance.

Regards.

Hi David,

First check the authorization for that folder on application server using the F.M.

Authorization_Check_dataset.

if sy-subrc Eq 0.

Then try to open the destination file.

if the size is different from source & target try with to open the dataset in TEXT MODE.

Messages Mess for finding the error message in the open statement.

Hi,

I solve the problem.

In fact, when I try to write the last line of lt_content, it does write all the line even if this line is not full of data.

Solution :


  DATA:  lv_file_name(100),
         lt_content LIKE sdokcntbin OCCURS 0 WITH HEADER LINE,
         alen TYPE i,
         pos TYPE i.

  MOVE '\mr0221TestA1.xls' TO lv_file_name.
  OPEN DATASET lv_file_name FOR INPUT IN BINARY MODE.
  IF sy-subrc NE 0.
    EXIT.
  ENDIF.

*--------------

  SET DATASET lv_file_name POSITION END OF FILE.
  GET DATASET lv_file_name POSITION pos.
  SET DATASET lv_file_name POSITION 0.
*--------------

  DO.
    CLEAR lt_content.
    READ DATASET lv_file_name INTO lt_content-line ACTUAL LENGTH alen .
    IF sy-subrc NE 0.
      APPEND lt_content.
      EXIT.
    ENDIF.
    APPEND lt_content.
  ENDDO.
  CLOSE DATASET lv_file_name.
*  DELETE DATASET lv_file_name.

*****************************************************

  CLEAR: lv_file_name.
  MOVE '\mr0221TestB2.xls' TO lv_file_name.
  OPEN DATASET lv_file_name FOR OUTPUT IN BINARY MODE.
  IF sy-subrc NE 0.
    EXIT.
  ENDIF.

  LOOP AT lt_content.
    AT LAST.
      TRANSFER lt_content-line TO lv_file_name LENGTH alen.
      EXIT.
    ENDAT.
    TRANSFER lt_content-line TO lv_file_name.
  ENDLOOP.
  CLOSE DATASET lv_file_name.

Thanks.
