Hi Katrin, after doing some data-cleanup we did the insert with SQL directly in the database. Thank you for this suggestion, Felix -----Ursprüngliche Nachricht----- Von: Koha [mailto:koha-bounces@lists.katipo.co.nz] Im Auftrag von Katrin Gesendet: Montag, 21.

I have found the initial bug report, maybe it has some useful information: Bug 7131 -way to overlay items in in marc import https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=7131 There is also a newer bug report: Bug 16828 - Item Overlay does not respect Bibliographic Record Match https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=16828 You could also use SQL to update the items in the database directly. If you choose this option, you should reindex after making the changes, so the indexes are up to date and you can search for the barcodes. Hope this helps, Katrin _______________________________________________ Koha mailing list http://koha-community.org Koha@lists.katipo.co.nz https://lists.katipo.co.nz/mailman/listinfo/koha
