Hy everyone,

     I want to delete a file from my PC after I upload it on the application server. This sould be done from the WebUI because i need it into the Netweaver Business Client.

     Thank you!

I've checked with this class and method and still doesn't work... I also tried GUI_DELETE_FILE but with no success...

I tried the class and method give above...this is successfully deleting the file.

can you check return code..if you ahve authorization?

I have give file path something like below.

C:\AMAR\TEST.TXT

lv_file_name = 'C:\todelete.txt'.

CALL METHOD cl_gui_frontend_services=>file_delete

    EXPORTING

      filename             = lv_file_name

    CHANGING

      rc                   = exceptions

    EXCEPTIONS

      file_delete_failed   = 1

      cntl_error           = 2

      error_no_gui         = 3

      file_not_found       = 4

      access_denied        = 5

      unknown_error        = 6

      not_supported_by_gui = 7

      wrong_parameter      = 8

      others               = 9.

this is how i use it for test purpose. The exception returned is not_supported_by_gui...

I think that the problem is that i run the nwbc/saplogon by a citrix server...

Hi,

You cannot use cl_gui* classes in Web Dynpro ABAP. These are only for SAPGUI, they require SAP GUI Framework.

If you are on Netweaver 7.01, you can use AcfExecute. Using this you can run the commands on the client machine.

Hope this helps u.,

Hi Kumar,

     Do you have some examples on how to use CL_WD_ACF_EXECUTE?

     Thank you!

Hi,

You can check my article here: http://scn.sap.com/docs/DOC-34524

You need to create a batch file to delete file in local machine and execute the batch file using AcfExecute. But it is static.

The problem is that i will obtain the name of the file dynamically, so i cannot create the batch file static...

[former_member184578 · Accepted solution]

Yes. That's what i mention. It is static. you cannot delete file dynamically. One option is creating/overwriting the  static batch file during upload with the name of file.

But again this is not possible using Web Dynpro ABAP.
