When creating an attribute in a processing, you can select the attribute type as a database column. This is great, as you can then select fields from the biblio, biblioitems or items table to be displayed in the train's table of items. I noticed that for fields linked to authorised values - Damaged status, Withdrawn, Collection, etc. - what displays in the train's table of items is the value, e.g. '4'. It would be more useful for the description to be displayed, as it is elsewhere in Koha.
Where do you see that? It looks good for me: https://snipboard.io/NZmb5D.jpg
Ha sorry, the DB columns!
