Listing files of directory on application server

Question

hi all,
I want to download a list of files from the application server.
I tried the functions:
- SUBST_GET_FILE_LIST
- EPS_GET_DIRECTORY_LISTING
- RZL_READ_DIR_LOCAL
but the result gives me the name of my file truncated.
My filename is much longer than the functions give me.
Is there any other function, or can i bypass this problem in a way.
Thanks in advance.
Merijn.

Hello,
This is a common problem with this FMs. Even SAP acknowledges this:
In EPS_GET_DIRECTORY_LISTING you have this:
data: begin of file,
        dirname(75) type c, " name of directory. (possibly truncated.)
        name(75)    type c, " name of entry. (possibly truncated.)
      end of file.
The FM uses a Kernel Call 'C_DIR_READ_NEXT' to get the list of the files in the directory. The file name is returned in the field file-name.
call 'C_DIR_READ_NEXT'
          id 'TYPE'   field file-type
          id 'NAME'   field file-name
          id 'LEN'    field file-len
          id 'OWNER'  field file-owner
          id 'MTIME'  field file-mtime
          id 'MODE'   field file-mode
          id 'ERRNO'  field file-errno
          id 'ERRMSG' field file-errmsg.
The program RSWATCH0(trxn: AL11) also uses the Kernel call but the structure file is different.
DIrectory name can be 1024 character long & file name is 260 character long
data: begin of file,
        dirname(1024)    type c,  " name of directory. (possibly
                                       " truncated.)
        name(260)        type c, " name of entry. (possibly
                                       " truncated.)
        type(10)    type c,            " type of entry.
        len(8)      type p,            " length in bytes.
        owner(8)    type c,            " owner of the entry.
        mtime(6)    type p, " last modification date, seconds since 1970
        mode(9)     type c, " like "rwx-r-x--x": protection mode.
        useable(1)  type c,
        subrc(4)    type c,
        errno(3)    type c,
        errmsg(40)  type c,
        mod_date    type d,
        mod_time(8) type c,            " hh:mm:ss
        seen(1)     type c,
        changed(1)  type c,
      end of file.
So one workaorund would be to copy EPS_GET_DIRECTORY_LISTING to some custom FM & change the length of the structure file to suit your requirement

PS: Use of Kernel Call is for internal use only & is highly not recommended by SAP.
