https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=32804 Bug ID: 32804 Summary: Importing and replacing items causes inconsistency when itemnumber match and biblio match disagree Change sponsored?: --- Product: Koha Version: master Hardware: All OS: All Status: NEW Severity: major Priority: P5 - low Component: Tools Assignee: koha-bugs@lists.koha-community.org Reporter: nick@bywatersolutions.com QA Contact: testopia@bugs.koha-community.org When 'Item processing' option during import is set to 'replace' itemnumber matches do not check any other data - so the item's biblionumber is set to the matched biblionumber, but the biblioitemnumber is not updated or checked This means that if you import a record containing an item with an itemnumber from another record you will end up with an item with mismatched biblio and biblioitem numbers This happens in consortia when multiple libraries have ordered the same biblio. Two biblios are created, later the final import with barcodes etc. is imported to replace items, and the more full bib is chosen for the biblio match, so items are half moved. To recreate: 1 - Be using the sample data in koha testing docker 2 - Stage the sample file on this report 3 - Match on KohaBiblio(999$c) / Item processing: replace 4 - Note the biblio match is "The complete novels / Austen, Jane" 5 - View the staged marc, note the barcode 39999000004090 in an item 6 - Search for that barcode 7 - You find biblio "Five novels : complete and unabridged / Gustave Flaubert" 8 - Import the file 9 - Check the db: SELECT * FROM items WHERE biblionumber != biblioitemnumber; 10 - Note the mismatch -- You are receiving this mail because: You are watching all bug changes.
