Description Jonathan Field 2023-07-04 15:43:55 UTC

In ERM Local Titles (cgi-bin/koha/erm/eholdings/local/titles) if you import from a List and that list has full MARC records, the creation of the ERM titles uses the data it can extract from the MARC records but then overwrites the source title. This means you may actually loose data in your MARC record because some of the data is not mapped. 

We should either retain the full MARC infomation from the original record or at least warn the user that they could potentially loose MARC data.

I don't understand why this action would change the MARC record at all - can you explain? It certainly sounds like a bug.

I half agree, I don't think it should update MARC fields that are absent from the KBART eholding local title, i.e. if you change the publication title in the eholding title, it should reflect to the biblio record linked to it, correct? But it should not strip all other existing MARC data in the linked biblio, as it currently does.

I opened bug 35115 before taking notice of this one and there's already WIP and discussion over there.

Ignore this comment, I mixed it up with a different (although somewhat related) bug 35095

Creating eholding local titles importing from a list of MARC records should not update the MARC records at all.
