Hi Von,
By default, alv filter line gives you "All" option for drop down field. Hence you no need to have "all" inside the range values of domain. So, you have only " X : Yes & - : No " as range values
You can filter it by either "Yes" or"No" and if you need to see all lines then choose "All" from drop down list
Hope this helps you,.
Regards,
Rama
