Code: Alles auswählen.

 bei Data: it_selected_rows TYPE salv_t_row hinzugefügt 
Des Weiteren habe über den o_salv->get_functions( )->set_all( abap_true ).
die Codezeilen: 
it_selected_rows = o_salv->get_selections( )->get_selected_rows( ).
go_salv->refresh( refresh mode = if_salv_c_refresh=>full ).
hinzugefügt, aber die go_alv gibt es nicht steht dort. Also habe ich versucht 
Data: go_salv TYPE und TYPE REF TO zu machen aber da kam nichts sinnvolles bei mir rum und ich weiß leider nicht was genau ich da reinschreiben muss. 

Liebe Grüße 
Nochmal herzlichsten Dank für alles.
