In order to test this, you need some shipments in your system (received orders with items and the like) Filters on the invoices page don't work correctly. For example a search by branch 'Midwäy' in my system results in 0 results with following errors in the log: [Sun Dec 02 15:24:52 2012] [error] [client 127.0.0.1] [Sun Dec 2 15:24:52 2012] invoices.pl: DBD::mysql::st execute failed: Unknown column 'aqorders.branchcode' in 'where clause' at /home/katrin/kohaclone/C4/Acquisition.pm line 2275., referer: http://localhost:8080/cgi-bin/koha/acqui/invoices.pl?op=do_search [Sun Dec 02 15:24:52 2012] [error] [client 127.0.0.1] [Sun Dec 2 15:24:52 2012] invoices.pl: DBD::mysql::st fetchall_arrayref failed: fetch() without execute() at /home/katrin/kohaclone/C4/Acquisition.pm line 2277., referer: http://localhost:8080/cgi-bin/koha/acqui/invoices.pl?op=do_search [Sun Dec 02 15:24:52 2012] [error] [client 127.0.0.1] [Sun Dec 2 15:24:52 2012] invoices.pl: Use of uninitialized value $searchstring in concatenation (.) or string at /home/katrin/kohaclone/C4/Bookseller.pm line 65., referer: http://localhost:8080/cgi-bin/koha/acqui/invoices.pl?op=do_search
