At the moment if the basket is still open you can update the bbliographic details of an order or overwrite the existing record via Z39.50, but if you notice that you have used the wrong record, there is no way to fix this. It would be great if it was possible to change the record an order is linked to while the basket is still open. This should explicitly allow to use a record that is already in the catalog. -- There is also a use case here for libraries using standing orders for tracking electronic resources such as series. They usually place the order on the series record. When the volumes arrive they'd like to change it so the acq information is tied to the volume. But without using items (which is not the case here for electronic resources), this is not possible.
