Cannot open application server file even if it exists...

aris_hidalgo — Tue, 22 Sep 2009 02:50:32 GMT

Hello Experts,

I cannot open a file residing in one of the directories in the application server

using command OPEN DATASET. The file is there but OPEN DATASET gives me a value of 8

in SY-SUBRC. Any solutions for this?

Do you have authorizations?

Thanks,

the path u mention is case sensitive... even the .txt or .dat is case sensitive...

to check the autho.. use CG3Y and CG3Z tr. to move to app to pres server and pres to app server...

Hi J@Y,

What I did was to use FM F4_DXFILENAME_TOPRECURSION then get the path and use it in OPEN DATASET. The file is existent when I checked using AL11. The cases is as is.

Hi,

I used CG3Y to read the file but it says "permission denied". Can I change my authorization to read this file or do I need the help of basis?

ok .. basis need to give u the permission.

Before opening dataset check file authority with FM AUTHORITY_CHECK_DATASET

CALL FUNCTION 'AUTHORITY_CHECK_DATASET'
      EXPORTING
        activity         = 'WRITE'
        filename         = filename
      EXCEPTIONS
        no_authority     = 1
        activity_unknown = 2
        OTHERS           = 3.

Hi J@Y,

I used your FM but its not giving me exceptions. I just tried in SE37.

Hi, Try this way to handle exceptions and gives what exactly the message is

REPORT  ZVENKAT_ALV_LIST.
PARAMETERS P_FILE(120) TYPE C.
DATA:OREF   TYPE REF TO CX_ROOT,
     TEXT   TYPE STRING.

TRY.
    OPEN DATASET P_FILE FOR OUTPUT IN TEXT MODE ENCODING DEFAULT.
*    IF SY-SUBRC NE 0.
  CATCH CX_SY_ARITHMETIC_ERROR INTO OREF.
    TEXT = OREF->GET_TEXT( ).
  CATCH CX_ROOT INTO OREF.
    TEXT = OREF->GET_TEXT( ).
*    ENDIF.

ENDTRY.
CLOSE DATASET P_FILE.
IF NOT TEXT IS INITIAL.
  WRITE / TEXT.
ENDIF.

Thanks Venkat.O
