Hello,could someone explain to me what is the meaning (functionnaly speaking) of this portion of code :
(C4/Circulation.pm)
# check if the book is in a permanent collection....
my $hbr = $iteminformation->{'homebranch'};
my $branches = GetBranches();
if ( $hbr && $branches->{$hbr}->{'PE'} ) {
$messages->{'IsPermanent'} = $hbr;
