Number interval for transaction & in CO area & almost exhausted

What causes this issue?

The number level for number interval &v3& - &v4& will soon reach the
upper limit. This number interval is assigned in controlling area &v2&
to business transaction &v1&.

System Response

The system will soon no longer be able to issue new CO document numbers.
Once the last CO document number within the number interval has been
assigned, the system will start again from the beginning of the
interval.
For example, if the interval is 001 to 099, numbering will start over at
001 once document number 099 has been assigned.
