Hi Jürgen,
sorry for not coming back to this earlier, I'm a bit busy at the moment. However, your hint regarding the residence time might be correct. Currently, it's set to 99999 days for all documents in the serial number history, which is probably why nothing is found when I try to write the archive file. Could that be correct? (Sorry for asking such simple questions, I don't have any experience at all with archiving.) If so, would it be a reasonable approach to lower these limits temporarily, so that the unwanted documents can be deleted, or can/should we do it permanently? We don't have recurring archive runs for serial numbers or serial number history, so changing the limits permanently should not have any unwanted side effects, right?
Thanks for your support!
