Final answer:
Bill segments in billing and invoicing systems can usually be regenerated in pre-final statuses such as 'Draft', 'Error', or 'Unposted'.
Step-by-step explanation:
The question 'What statuses can bill segments be regenerated?' pertains to the process in billing and invoicing systems, most likely within a software or finance-related context. Bill segments can usually be regenerated in certain statuses to correct errors or to update the segment information.
The specific statuses in which bill segments can be regenerated can depend on the system being used, but common statuses may include 'Draft', 'Error', or 'Unposted'.
There may be systems that allow regeneration in other statuses with the proper permissions. In most billing systems, once a bill segment has reached a 'Finalized' or 'Posted' status, it typically cannot be regenerated without reversing the posting. Usually, only bill segments in preliminary, non-committed states can undergo regeneration.
