No CO-document number assignment (CO area &, activity &)

What causes this issue?

The system cannot allocate CO document nubmers for transaction &v2& in
controlling area &v1&.
This is the result of either a system error or inconsistent data
constellation.

How to fix this error?

Start the program RKTKA04C using the menu function "System -> Services
-> Reporting".
Maintain the number ranges for CO documents for controlling area &v1&
("CCA System Configuration -> Environment -> CO
document no. range").
Create new number range groups if required, and assign business
transaction &v2& to a number range group.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

If you cannot find business transaction &v2&, you should report the
error to SAP.
