Hi,

Go to AL11 and open your file and copy the path of the file, dont make any change like letters from upper case to lower and vice versa in the file name. And use the same in the statement of open dataset.

Cheers,

check if u are opening the same file multiple times, if yes call CLOSE_DATASET after first one.

Also u can use try--catch block to have a soft termination.

try.

open dataset < >

< processing here>

catch CX_SY_FILE_OPEN.

< message handling here>

endtry.

Hi ,

You might have opened the file (ex: notepad if text file) outside. Check it. If so close it and execute the program. If still problem exist, try to use CLOSE DATASET before OPEN DATASET.

Hope sytanx is written as OPEN DATASET filename FOR INPUT IN TEXT MODE.

Hi,

If the R/3 System is ruining under UNIX, If sy-subrc is 8.

The system cannot open the file, since the name you specified is that of a directory.

So check the path.
