[BadrAly]

• Fixes Add some fields to the Inventory list #2704
• Fixes Inventory list export: some columns counts only use active loans #2793

Co-Authored-by: Aly Badr aly.badr@rero.ch

How to Test:

• run the Inventory list report for a given instance.
• the fields extracted from the document record are now prefixed with the string document_
• the fields extracted from the item record are now prefixed with the string item_
• the local_fields are now extracted for both documents and items
• all the fields mentioned in the issue Add some fields to the Inventory list #2704 are added
• loan information are correctly extracted according to Inventory list export: some columns counts only use active loans #2793

Tests

• document_series_statement and document_edition_statement are not exported (column stays empty)
• document_local_fields not exported (column stays empty)
• temporary_item_type not exported (column stays empty)
• Item 1611 has a checkout date but last_transaction_date is empty. Why?
• LAU: It is better to have all dates in the same format.
• REP 29.06: Items of type issue are not exported anymore. Try filtering by "serial" in AOSTE-CANT1, there are 79 issues in the interface but the file is empty. Cannot test the issue related columns.
  • JD 29.06 : The "Late issues" export doesn't work either (no data export).
• REP 29.06 : item_status stays empty
• NPR 29.06: within document and item local fields: if more than one value, values should be concatenated with | as for the other fields.

Great job ! Thank you.

Cosmetic remark:

• please move the first 2 columns (item_pid and item_create_date) and try group them with the other Item columns.
  => The purpose is to get Document info, then Item info, then loan infos.
