Was verursacht dieses Problem?

For the selected line layout, the system configuration settings do
not contain any specifications concerning the fields by which sorting
is to be carried out.

Wie behebe ich diesen Fehler?

You may want to choose a line layout that permits sorting (if so,
choose <LS>Settings</> --> <LS>Line layout</>).
If you want to perform a sort for the set line layout, you must ask
your system administrator to change the display variant in the
Customizing system of Invoice Verification. For the line layout, you
can enter the fields that are to be offered as sort criteria (via
<LS>Environment</> --> <LS>Field selection</> --> <LS>Sort</>).
