What causes this issue?

Document classes exist that are not assigned to a number range interval.
This can occur in the following cases:
You have created document classes that are not to be used for official
document numbering.
You have not assigned each document class to a number range interval
even if the document class requires an official document number.

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

System Response

The system cannot determine whether a Customizing error has occurred,
and it proceeds with official document number processing. The system
does not assign an official document number to a document if it belongs
to a document class that is not assigned to a number range interval.

Procedure for System Administrators

  Changes in Document Classes: If new document classes were added without corresponding number range intervals being created.
  Transport Issues: If changes were transported from a development environment to a production environment without ensuring that the number ranges were
