At the moment we use standing orders for multi-volume and series ordering mostly. The order is placed on the set or traced series record. When a part of the series is delivered and received, the order line will still be linked to the set records. This makes all acquisition information appear on the set record, instead of the parts. If you are using items, you can use the "attach item" feature, to change it to the record of the part, but this means a lot of additional clicks. It will also not work if you are not creating items in acq. It would be nice, if you could link the received order line to the correct part as part of the receiving process.
