Former Member — Mon, 29 Sep 2008 14:09:33 GMT

Hi,

I have a problem at the background execution of my program. I have this error : "OBJECTS_OBJREF_NOT_ASSIGNED"

Information on where terminated

Termination occurred in the ABAP program "SAPLCNDP" - in

"DP_CONTROL_ASSIGN_TABLE".

The main program was "ZFI__SAPHIR_ES_SPLIT_TRIP_HEAD ".

In the source code you have the termination point in line 1

of the (Include) program "LCNDPU10".

The program "SAPLCNDP" was started as a background job.

Job Name....... "ZFI__SAPHIR_ES_SPLIT_TRIP_HEAD"

Job Initiator.. "COULOUMIESXA"

Job Number..... 15580300

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!

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...

>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)?

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!

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 — Tue, 30 Sep 2008 09:41:30 GMT

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...
