We are looking for a way to apply batch updates to Millennium item records outside the system.
We would like to create a new shelf mark field containing a unique running number in c.8000 items in a review file. I don't think this can be done within the system using global updates. The documentation implies that to get at item information outside Millennium we would have to export and reload item data attached to bib records, but this would create problems running the updates.
We know we can export item records on their own in MARC format via Data Exchange, and a colleague tried an item overlay using a local load profile for another project but got some unexpected results.
Has anybody attempted importing/overlaying items using load profiles, or know if it is possible?
