I'm importing data of movements to tch. The portal is fine, but I strongly recommend to display after the ID the field 'motive/exhibition' (rsc715). In general it seems that is the field which includes the key information about the movement. In fact is the first field displayed when browsing directly the movements section. If very difficult to understand the movement without that field. If you have to remove one, maybe return date is not so relevant.
It seems that is also the most important one for retrieving records from the autocomplete, where is not present.
The same solution it's interesting for the movements record itself, where 'motive/exhibition' (rsc715) is the last field of the first line. The first position seems a better choice.
