Currently the code for displaying locations and collection in the patron checkouts table doesn't handle the case when there is no authorised value in LOC or CCODE. > + my $collection; > + if ( $c->{collection} ) { > + my $av = Koha::AuthorisedValues->search({ category => 'CCODE', authorised_value => $c->{collection} }); > + $collection = $av->count ? $av->next->lib : ''; We could make this a little better by displaying the stored value when no match is found in the authorised value list.
