I've made additional save button for ALV screen. Button is described within GUI-status.
FORM user_command USING u_ucomm TYPE sy-ucomm
CHANGING c_selfield TYPE slis_selfield.
Data: lv_is_bayer TYPE c,
lt_rows type salv_t_row.
CASE u_ucomm.
WHEN '&SAVE'.
But it's not working, despite the fact, that the same code in another project executing just fine. In debugging mode there's no access to that part of code on button pressed. So, where should i look for the problem?
