>Subject: [PATCH] Bug 32804: Do not adjust biblionumber when replacing items
> during import
>
>This patch adjust the item matching at import to confirm that for a duplicate itemnumber or barcode
>matches an existing item in the DB and uses the original biblionumber when updating the item.
>
>When ordering in a consortium the items may be moved around, duplicate biblios added, and various matches found.
>We should not allow importing of items to move them from 1 biblio to another, but  we should allow the imports
>to succeed and assume itemnumber or barcode matches are authoritative. The responsibility for correct matching of items to biblio should fall on the creator of the files
>
>To test:
> 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
>11 - Fix the item and set it as 'Music' type
>     UPDATE items SET biblionumber = biblioitemnumber, itype='MU' WHERE biblionumber != biblioitemnumber;
>12 - Apply patch, restart all
>13 - Stage and import the file with the same settings
>14 - Confirm the item is modified on its original biblio (99) and that item type is Book again
>15 - Change itemnumber to avoid itemnumber match and reset type
>     UPDATE items SET itype='MU', itemnumber=999 WHERE itemnumber=212;
>16 - Stage and import with the same setttings
>17 - Confirm the marcode match worked and item is updated to book on original record
>18 - Delete the original item
>19 - Stage and import the file with the same settings
>20 - The item is successfully created
>21 - Stage and import, but item processing option is 'add'
>22 - Confirm 1 item ignored
>23 - Check the db
>     SELECT * FROM import_items WHERE barcode=39999000004090
>24 - Confirm there is a line with 'error' and duplicate_barcode
