[Koha] NULL items

Thanks Chris, I meant to also state that our Koha was recently updated to I verified that item-level_itypes is set to Use the item type of the Specific Item. I couldn't find biblioitems.itemtype in Systems Preferences but under Koha to MARC Mapping > biblioitems itemtype is mapped to 942c. I'm assuming that these are as they should be.

Since I'm just a librarian ;-) I asked my geek to walk me through the Update and Script recommendations you make; she'll be in this afternoon.

Changing the 942c and 952y does not seem to alter the NULL; the Catalog Statistics report result number does not change. Additionally, any idea how I managed to have so many NULL items.itypes; could it be my adding a space prefix to Description when in Modify Item Type so that alphabetically the most used itype is the first choice?
Hi Rachel

There are 2 things you can check here, do you have item-level_itypes set?
And is biblioitems.itemtype set?

You probably want to item-level_itypes switched on, then to populate them
If so, a good start would be to run
UPDATE items,biblioitems SET items.itype=biblioitems.itemtype WHERE

That will fix the items table, there is then a script in
misc/maintenance called sync_items_in_marc.pl which when run will fix
the MARC to match what you have in the items table.

Hope this helps
