It is possible to create serial item with wrong itemtype if syspreference
makePreviousSerialAvailable is enabled and field "item type for older issues"
isn't filled when creating a subscription for biblio record. This happens
when multiple items are created. In installations where itemtypes differ
between items and biblios, this causes data inconsistencies and leads to
errors in biblios Holdings table.
This patch changes behaviour of serials-edit.pl so that if
makePreviousSerialAvailable is enabled and subscriptions previousitemtype
column is NULL, previous serial items itype column is preserved. It also
adds a hint text to subscription form about this change.
To test:
1. Enable systempreference makePreviousSerialAvailable.
2. Create new biblio record.
3. Create a new subscription for biblio record you made, select option
"Create an item record", select different item type from "Item type"
selection than biblio record has but leave selection "item type for older
issues" empty.
4. Receive a serial item for subscription. Check from biblio records
Holdings table that its item type matches item type selected in step 3.
5. Now receive 3 serial items. After creating them check Holdings table again.
=> Note that first item created now has same item type as biblio record.
6. Apply this patch, restart services.
7. Create new subscription, fill needed fields as in step 3.
=> Note that there is a new hint text after field "item type for older issues".
8. Repeat steps 4. and 5.
=> Note that now all items have same item type.
