GUI_* WS_* Function In Background, CSV Upload
GUI_* and WS_* function modules do not work in background
When scheduling a job in the background the appropriate statement to read in your file is OPEN DATASET, and the file must be on the file system that the SAP server can see.
At anytime, a user can switch of the Personal Computers even though the job is still running in the background.  Therefore GUI_* and WS_* function modules are not designed to work in that way, as they need to access your personal computer  file.
To choose the correct download method to used, you can check the value of SY-BATCH in your code,
if it is 'X' use OPEN DATASET and if it is ' ' use WS_UPLOAD.
*-- Open dataset for reading
DATA:
  dsn(20) VALUE '/usr/test.dat',
  rec(80).
OPEN DATASET dsn FOR INPUT IN TEXT MODE.
IF sy-subrc = 0.
  DO.
    READ DATASET dsn INTO rec.
    IF sy-subrc <> 0.
      EXIT.
    ELSE.
      WRITE / rec.
    ENDIF.
  ENDDO.
ENDIF.
CLOSE DATASET dsn.
*-- Open dataset for writing
DATA rec(80).
OPEN DATASET dsn FOR OUTPUT IN TEXT MODE.
  TRANSFER rec TO '/usr/test.dat'.
CLOSE DATASET dsn.
What is the difference when we use upload, ws_upload, gui_upload function modules?
UPLOAD, WS_UPLOAD, GUI_UPLOAD, are used in BDC concepts.  ie., Batch Data Communication.
Batch Data Conversion is a concept where user can transfer the Data from non SAP to SAP R/3.  So , in these various Function Modules are used.
UPLOAD---  upload a file to the presentation server (PC)
WS_UPLOAD----    Load Files from the Presentation Server to Internal ABAP Tables.
WS means Work Station.
This is used upto SAP 4.6 version.
GUI_UPLOAD-------    Replaces WS_UPLOAD. Upoad file from presentation server to the app server.  From 4.7 SAP version it is replaced.
