--- Comment #19 from David Nind <[email protected]> ---
Thanks Angela and Nick! (For reporting, finding the cause, and letting us
know!)

It is great to have some more things that libraries can look for to try and
resolve holding table loading issues and errors.

Check the 'item-level_itypes' system preference setting
=======================================================

If set to 'specific item', then all items must have a valid 952$y value (item
add form for MARC21 installations: y - Koha item type).

If set to 'bibliographic', then all bibliographic records must have a valid
942$c value (for MARC21 installations, tab 9, 942$c - Koha item type).

(Or equivalent UNIMARC tags and subfields.)

The reason records and items may not have these values could include: 
. the frameworks were edited, and these tags and subfields were not made
mandatory (or removed)
. previous data imports were missing these values (I think the import process
it is a bit more rigorous now)
. previous cataloging (adding new records and items), where these fields were
not mandatory

The misc/maintenance/search_for_data_inconsistencies.pl script can identify
missing item types.

A report to help identify missing values (from the SQL Library - Items missing
an item type or record missing an item type), although the
search_for_data_inconsitencies script is probably better:

SELECT title, biblionumber, barcode, itemcallnumber, itemnumber
FROM items
JOIN biblio USING (biblionumber)
LEFT JOIN biblio_metadata USING (biblionumber)
WHERE itype IS NULL
OR ExtractValue(metadata,'//datafield[@tag="942"]/subfield[@code="c"]') = ''

Review any plugins that you have, or temporarily disable
========================================================

Plugins (Koha administration > Plugins > Manage plugins) may interfere with the
display of items in the holdings table.

Some options include:
- Temporarily disabling suspect plugins to help identify if any are interfering
- Reviewing and updating plugins that interact with the holdings table
