Hi Koha Community, I'm currently using Koha 3.2.X with UNIMARC configuration in many installations and everything is working fine. Today one of the clients asked if it's possible to search by the record creation date and the last modification date. I've checked the UNIMARC configuration and the record.abs and told then that what they want it's possible. There are entrances in the record.abs to the 099$c and 099$d, which sould be the record creation date and the last modification date. The problem is that the marcxml (column in the biblioitems table of the database) in any record doesn't have the 099 field. The values are filled in the biblio table, but should also be in the marcxml (to be indexed by Zebra in order to be searchable). There is any configuration to fill the 099 automatically in the creation or in the editing? Anyone have this working? Best regards. Vitor Fernandes
