Regarding downloading file on application server ?

Question

i am using open data set and close data set to create file on application server.
the program is compiling fine, but when i execute it, it throws a dump saying
DATASET_NOT_OPEN  , it says that the file is not open.
when i check value of sy-sub-rc it is 8. no file on server.
i want to create a dynamic file name, like i want to append the sy-cdate to the file name, so that when i schedule my program every day, i will create a new file.
what is the t-code to look at directories on app server. i tried al11, but couldnt find mine..but the basis said they had already created a folder for me there.

Hi,
May be you don't have write permission for the corresponding folder on the application server. thats why you could not create file on that folder.so ask you basis people for read/write permission on the that destination folder..
For creating dynamic file , you can use logical file and physical file concept..
for each interface maintain a logical file name in a ztable and ask your basis people to maintain a physical file path on application server for each logical file name.(using FILE Txn).
first get the logical file name from ztable then get corresponding physical path onapplication server using FM 'FILE_GET_NAME' and finally concatenate the sydatun to physical file name...
DATA: l_file_folder TYPE string,
        l_logical_file TYPE fileintern,
  CLEAR: file1.
*<b> First get the logical file name from table zabc021</b>
  SELECT SINGLE log_file " Actual file location
                     INTO l_logical_file
  FROM zabc021
  WHERE interface = p_interface
    AND inorout = 'O'. "outbound interface
<b>* Get the physical file name from the logical file name</b>
  CALL FUNCTION 'FILE_GET_NAME'
    EXPORTING
  CLIENT                        = SY-MANDT
      logical_filename              = l_logical_file
   IMPORTING
     file_name                     = l_file_folder
   EXCEPTIONS
     file_not_found                = 1
     OTHERS                        = 2
  IF sy-subrc = 0.
<b>* In actual situation the file name should come from FILE txn</b>
    CONCATENATE l_file_folder
    p_interface '_' sydatum4(2) sydatum6(2) '.DAT' INTO file1.
  ELSE.
    CLEAR file1.
    MESSAGE s999 WITH 'No logical file maintained with name ' l_logical_file.
    EXIT.
  ENDIF.
now file1 is the file name.
I hope this info is useful to you...
