Process every file in a directory

[Former Member]

Is there a way to "read" every file (csv) file in a directory on the server (a background job)? I will never know the number of files on the server during any given run. Is there a way to "loop" through a directory or bring the filenames into a table and loop through that table? Basically I will have many csv files, each one being an order, and I will be processing these files (orders) each night. I realize that I will need to use a dataset but how do I get to the files?

Hi,

Please check this sample code.

REPORT  ZDIRFILES.

PARAMETER: p_fdir type pfeflnamel DEFAULT '/usr/sap/tmp'.

data: begin of it_filedir occurs 10.
        include structure salfldir.
data: end of it_filedir.

START-OF-SELECTION.
* Get Current Directory Listing for OUT Dir
  call function 'RZL_READ_DIR_LOCAL'
    exporting
      name     = p_fdir
    tables
      file_tbl = it_filedir.

* List of files are contained within table it_filedir
  loop at it_filedir.
* Here you process the file individually
    write: / it_filedir-NAME.
    ...  

  endloop.

Ferry, that is beautiful! I could give you a hug for that!!!

A quick follow up. Can you move files and create directories in ABAP?

This would create the directory but what about moving/renaming a file?

call function 'GUI_CREATE_DIRECTORY'
     exporting
dirname = '//<ip_address>/qfilesvr400/<host>/usr/sap/TST/SYS/Folder1'
     exceptions
          failed  = 1
          others  = 2.

Hi,

You can use SYSTEM command/function.

DATA: UNIX_COMMAND(500).

DATA: BEGIN OF ITAB OCCURS 0,
        LINE(255),
      END OF ITAB.
                                                                        
CONCATENATE 'mv' SOURCE_FILE DEST_FILE INTO UNIX_COMMAND
                                       SEPARATED BY SPACE.
                                                                        
CALL 'SYSTEM' ID 'COMMAND' FIELD COMMAND ID 'ITAB' FIELD TABM-*SYS*.
