The system performs checks before archiving serial number histories:

• It checks whether the following documents, for which a serial number history exists, have already been archived:

• Deliveries
• Sales documents
• Goods movements
• Inspection lots
• Production or refurbishment orders
• Handling units
• Physical inventory documents

• It checks whether the residence times for documents in the serial number history has already elapsed.

If these conditions are not met, the system cannot archive the serial number history. As a large number of histories are frequently archived in the area of serial numbers, for reasons of performance you will not receive a message that a history cannot be archived.
