FileFilter in cl_gui_frontend_services=>directory_list_files doesn't work

[ventior]

For some reason whenever I use a file filter in the function "directory_list_files" of "cl_gui_frontend_services" it doesn't seem to work, while in methods like "file_open_dialog" there is no such problem.

If I leave out the filter in the code below it lists all files in the directory as usual, but when I use the filetype_excel filter all files vanish, including XLSX and XLSM files while still giving a sy-subrc of 0.

Is there a note regarding this problem? I read of note 864592, but it seemingly has been removed.

cl_gui_frontend_services=>directory_list_files(
  EXPORTING
    directory                   = lv_directory                 " Directory To Search
    files_only                  = abap_true
    filter                      = cl_gui_frontend_services=>filetype_excel          " File filter

What about all the other SAP notes?

2868986 - DIRECTORY_LIST_FILES method is not working with multiple filter values

etc.

Do you have a S-User?

Try using filter '*.XLS*' it worked on my systems.

Yes, works perfectly along the note sandrarossi commented. Thank you for your help!

It seems this particular note has flown over my head. Thank you for showing me.
