You can't use an inline declaration with the parameters of type CHANGING and EXPORTING in method calls.

The ABAP documentation doesn't say it explicitly, but mentions explicitly that inline declaration can be used for parameters of type IMPORTING and RECEIVING, with some limitations, without saying anything about the two other types.

There was extensive discussions here and here.

Examples of possible inline declarations with method calls:

cl_gui_frontend_services=>FILE_GET_ATTRIBUTES
    EXPORTING
      filename = `C:\test.txt`
    IMPORTING
      readonly = DATA(readonly) ).
cl_ixml=>create(
    RECEIVING
      rval = DATA(ixml) ).

Concerning EXPORTING or CHANGING, you have to deal with the old declarations. Example:

DATA lv_desktop TYPE string.
cl_gui_frontend_services=>get_desktop_directory(
    CHANGING
      desktop_directory = lv_desktop ).
