Are you trying to read a file from your PC?

Files stored on your PC are presentation server files and should be read using the FM WS_UPLOAD or GUI_UPLOAD.

Unix files or Application server files are read using OPEN DATASET statement. These files can be seen in transaction AL11.

Hi,

Use this FM GUI_DOWNLOAD.

Declare an interna table same as your File in the program.

Sample code is given below:-


CALL FUNCTION 'GUI_UPLOAD'
  EXPORTING
    filename                      = filepath
*   FILETYPE                      = 'ASC'
    has_field_separator           = 'X'

   TABLES
                       data_tab   = i_tab


 EXCEPTIONS
   file_open_error               = 1
   file_read_error               = 2
   no_batch                      = 3
   gui_refuse_filetransfer       = 4
   invalid_type                  = 5
   no_authority                  = 6
   unknown_error                 = 7
   bad_data_format               = 8
   header_not_allowed            = 9
   separator_not_allowed         = 10
   header_too_long               = 11
   unknown_dp_error              = 12
   access_denied                 = 13
   dp_out_of_memory              = 14
   disk_full                     = 15
   dp_timeout                    = 16
   OTHERS                        = 17
          .
IF sy-subrc <> 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
*         WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.

Hi Vijay,

As the previous guys mentioned, we can use OPEN DATASET for the files on the Application server only.

But instead of changing the entire code, u can put the same file in the application server & use the same code.....

Use the transaction CG3Z for uploading the files in presentation server to Application server.

But specify a filepath (in which u want to upload the file in AL11 transaction) in the same transaction CG3Z.Then in that path, the file will be stored. Then u assign that filepath to FNAME in ur program. This will surely works.

Try this & let me know in case of any issues.

Dont forget to reward points if helpful.

Pavan.
