ABAP verification.

Good morning.

I searched in sdn but I didn´t find the solution for that question:

In my program i  doing extended program check of program and I try to correct, but the error remains.

CALL METHOD cl_gui_frontend_services=>file_save_dialog

     EXPORTING

       default_extension = '.txt'  "#EC NOTEXT

       file_filter       = 'Arquivo de Texto (*.txt)|*.TXT|' "#EC NOTEXT

     CHANGING

       filename          = v_nada

       path              = v_path

       fullpath          = v_nda

       user_action       = v_act

     EXCEPTIONS

       cntl_error        = 1

       error_no_gui      = 2

       OTHERS            = 3.

why my "#EC NOTEXT don´t work , the error remains.

Thanks for help.
