Function/method for getting directory list

h_senden2 — Fri, 04 Jan 2008 09:04:55 GMT

Hi,

i'm looking for a function module or class method for getting all files (or with a filter) from a directory on the application server. I have found the function EPS_GET_DIRECTORY_LISTING and RZL_READ_DIR_LOCAL, but both are not working for files with names longer than 32. And my filenames are at least 50 characters long.

Anyone ?

regards,

Hans

Hans,

try sth like this:

FUNCTION Y_GET_DIRECTORY_LISTING_HP_UX.

*"----

""Lokale Schnittstelle:

*" IMPORTING

*" VALUE(DIR) LIKE RLGRAP-FILENAME OPTIONAL

*" VALUE(FILE_MASK) LIKE RLGRAP-FILENAME DEFAULT SPACE

*" EXPORTING

*" VALUE(DIR_NAME) LIKE RLGRAP-FILENAME

*" VALUE(FILE_COUNTER) LIKE EPSF-EPSFILSIZ

*" VALUE(COMMAND) LIKE RLGRAP-FILENAME

*" TABLES

*" DIR_LIST

*" EXCEPTIONS

*" DIR_NOT_EXIST

*" NO_AUTHORIZATION

*" READ_DIRECTORY_FAILED

*" EMPTY_DIRECTORY_LIST

*" FALSE_OS

*"----

DATA: NAME like rlgrap-filename.

data: lv_mgr_user type as4user.

DATA: BEGIN OF TABL OCCURS 0, "Table for system-call

LINE type string,

END OF TABL.

authority check

call function 'TMS_CI_GET_USER_INFO'

IMPORTING

ev_mgr_user = lv_mgr_user.

call function 'TR_AUTHORITY_CHECK_ADMIN'

EXPORTING

iv_user = lv_mgr_user

iv_adminfunction = 'EPS1'

EXCEPTIONS

others = 1.

IF SY-SUBRC <> 0.

RAISE NO_AUTHORIZATION.

ENDIF.

*nur für HP-UX und AIX

if sy-OPSYS <> 'HP-UX'.

raise false_os.

endif.

dir_name = dir.

concatenate dir_name file_mask into name separated by '/'.

concatenate 'ls' name into command separated by space.

CALL 'SYSTEM' ID 'COMMAND' FIELD COMMAND

ID 'TAB' FIELD TABL-SYS.

dir_list[] = tabl[].

describe table dir_list lines file_counter.

IF FILE_COUNTER > 0.

SORT DIR_LIST.

ELSE.

RAISE EMPTY_DIRECTORY_LIST.

ENDIF.

ENDFUNCTION.

Hi Andreas,

thanks for your reply. It seems that are no standard SAP functions to do this job ?

I believe that we don't have a HPUX system but Linux. Is it still working ?

But i'm going to try it

regards,

Hans

The system command doesn't return a proper result.

I'm going to try to rewrite the function RZL_READ_DIR_LOCAL for filename with lenght 128 or so.

...or try without these line:

~~raise false_os.~~

Hai,

You can use function module TMP_GUI_DIRECTORY_LIST_FILES

Sample Code:

data:

DIR_NAME LIKE RLGRAP-FILENAME,

FILE_MASK TYPE C DEFAULT SPACE,

file_table TYPE sdokpath OCCURS 0 WITH HEADER LINE,

dir_table TYPE sdokpath OCCURS 0 WITH HEADER LINE,

fullpath TYPE sdokpath.

REFRESH file_paths.

CALL FUNCTION 'TMP_GUI_DIRECTORY_LIST_FILES'

EXPORTING

directory = dir_name

filter = file_mask

IMPORTING
FILE_COUNT =
DIR_COUNT =

TABLES

file_table = file_table

dir_table = dir_table

EXCEPTIONS

cntl_error = 1

OTHERS = 2.

IF sy-subrc <> 0.

*No_file_exists

ENDIF.

IF ( NOT dir_name CP '*\' ).

CONCATENATE dir_name '\' INTO dir_name.

ENDIF.

LOOP AT file_table.

CONCATENATE dir_name file_table-pathname INTO fullpath.

APPEND fullpath TO file_paths.

ENDLOOP.

LOOP AT dir_table.

CONCATENATE dir_name dir_table-pathname INTO fullpath.

APPEND fullpath TO file_paths.

ENDLOOP.

___________________________________________________________________________________

You can use function module 'RZL_READ_DIR_LOCAL'.

Sample code:

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.

Note: for unicode (ECC 6.0), we have to add "ENCODING DEFAULT" with "open dataset ".
