Bug ID: 43907
Summary: Reverting a staged MARC import deletes the existing
items that the import replaced
Initiative type: ---
Sponsorship ---
status:
Product: Koha
Version: Main
Hardware: All
OS: All
Status: NEW
Severity: major
Priority: P5 - low
Component: MARC Bibliographic record staging/import
Assignee: [email protected]
Reporter: [email protected]
QA Contact: [email protected]
Depends on: 43905
Target Milestone: ---
When a staged MARC import is committed with the item action "replace",
existing items are replaced: the item is found by its itemnumber (952$9)
or by its barcode, and updated. These items already existed before the
import, and can be attached to another record.
Reverting the batch then deletes the items listed in import_items for
each record, but import_items does not distinguish the replaced items
from the items created by the import (both have the status 'imported'):
- If the item was matched by itemnumber, import_items.itemnumber is the
existing item, so reverting the batch DELETES THAT EXISTING ITEM.
- If the item was matched by barcode, import_items.itemnumber gets the
952$9 of the incoming file (usually empty) instead of the replaced
item, so the item is not deleted, but the link is wrong (and it could
point to an unrelated item).
To reproduce:
1. Cataloging > Stage records for import: stage a file with a record
that matches an existing record (for example by ISBN), with a 952
with the itemnumber (952$9) of an existing item of any record,
choosing "Replace items if matching bib was found".
2. Cataloging > Manage staged records: import the batch. 1 item is
replaced.
3. Undo the import of the batch: the existing item is deleted (it is
now in deleteditems).
