Frontend services will fail in Background, because of that you are getting the error in background.

You say that I can't use cl_gui_frontend_services method?? I use this metho (upload_file, download_file, delete_file...) for my program. It's mandatory!

[former_member188685]

then you may have to work with application server files(open dataset , Close dataset, Transfer, Read ) not the Presentation server files. Those methods will fail in background.

There is a document using using the approach you can try , but that is lengthy approach. check it here..

I don't understand your approach... Can I use frontend services methods? I don't use Open dataset, Transfer or Read! I used upload_file, download_file, directory_list_files, file_copy, file_delete methods...

[former_member188685]

>Can I use frontend services methods?

No in Background processing

if you still want to use then try the approach mentioned here..

In fact, I need, in my program, to create a filter to retrieve several files in a directory. So, with CL_GUI_FRONTEND_SERVICES, I used directory_list_files method. But, as you say, this method failed in background. So, my question is, how retrieve files name selected by the filter (ex : *.txt)?

[Former Member]

How do I retrieve a file list in background without use directory_file_list method?? I try this code of the RSWATCH0 program:

CALL 'C_DIR_READ_START' ID 'DIR' FIELD a_dir_name

ID 'FILE' FIELD a_generic_name

ID 'ERRNO' FIELD file-errno

ID 'ERRMSG' FIELD file-errmsg.

DO.

CLEAR file.

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.

ENDDO.

But, I retrieve files of SAP server random... I don't retrieve my files!

[former_member188685]

I don't think you can do that. There is no straight forward solution to it. did you read the article mentioned above.

[Former Member]

I try your solution but, it don't work! The function RFC_REMOTE_FILE doesn't exist, there isn't destination server and in input, there is a file but I need a directory in input...
