If the KBART file imported contains an optional column not defined by the format (like "bestpnn" column present in KBART files imported from https://bacon.abes.fr/ ), this information is lost by Koha, while it may be useful. We could store it in that way : - give the ability to create additional custom fields for ERM titles (like agreements or packages) - give the ability to map an optional KBART column with the custom field
I like the idea of using additional fields for this with a mapping on the name of the column. GOKb also uses additional fields in their KBART exports and storing that information could be very useful.
Addidtional fields for ERM titles are available since 26.05 see Bug 40192
