Hi Dominik,
How did you get the value help. if it is through a search help than you need to take care of this there. If you have added a key-value pair table in Get v then you can fill the value pair table such that you pass the value of key in the value field.
Like. ls_tab-key = 'AU'.
ls_tab-value = 'AU'.
