Class to Get File List from Application Server

[antonio_sanseverino]

Hi all

I've to obtain the file list of a directory from application server, I can use a FM too but It's possible the lenght of file name is upper then 40 characters so I can't use FM EPS_GET_DIRECTORY_LISTING.

Thanks

Try using the function RZL_READ_DIR_LOCAL. Here is an example program using this function.

data: begin of itab occurs 0,
      rec(1000) type c,
      end of itab.
data: wa(1000) type c.

data: p_file type localfile.
data: ifile type table of  salfldir with header line.

parameters: p_path type salfile-longname
                    default '/usr/sap/TST/DVEBMGS01/data/'.


call function 'RZL_READ_DIR_LOCAL'
     exporting
          name           = p_path
     tables
          file_tbl       = ifile
     exceptions
          argument_error = 1
          not_found      = 2
          others         = 3.

loop at ifile.
  format hotspot on.
  write:/ ifile-name.
  hide ifile-name.
  format hotspot off.
endloop.


at line-selection.

  concatenate p_path ifile-name into p_file.

  clear itab.  refresh itab.
  open dataset p_file for input in text mode.
  if sy-subrc = 0.
    do.
      read dataset p_file into wa.
      if sy-subrc <> 0.
        exit.
      endif.
      itab-rec = wa.
      append itab.
    enddo.
  endif.
  close dataset p_file.

  loop at itab.
    write:/ itab.
  endloop.

Hello,

A few days back we had a discussion the same issue. You can use an external system command to get the "xxtra-long" file names from the app server w/o getting the sames truncated.

Both EPS_GET_DIRECTORY_LISTING & RZL_READ_DIR_LOCAL have limitations on the maximum length of the filename.

Cheers,

Suhas
