[Koha] problem with new feature - write protecting MARC fields

[Isabel Pineda]

Hi.

I am trying the new feature that protects MARC fields from overwriting. It works for me with the module "user category", but I cannot get it to work with the "source" module. I would like to protect the 856 field from overwriting during a Z39.50 import. Is this a bug?

Thank you
