Message text: New NR interval &1 created in the target subobject
The system creates a new number range interval in the target subobject,
and copies it to table NRIV after the conversion.
The system generates number range interval mapping values from existing
subobject mapping values. As a rule, the system does not change the
number range Customizing settings of a reference subobject (the
subobject that takes priority in the merge group). However, there are
some cases where the system has to create new intervals in the target
subobject in order to provide consistent mapping values:
If the number range exists in one of the source subobjects but does not
exist in the reference subobject (see example 1 below).
or
If the number range intervals of the source and reference subobjects are
differently distributed over fiscal years (see example 2 below).
In both cases, the system creates new number range intervals and saves
them in internal tables. The system only copies these new intervals to
table NRIV after the conversion.
The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

The SAP error message CNV_NCE_BAS243 indicates that a new number range interval has been created in the target subobject during a data migration or conversion process. This typically occurs in the context of using SAP's data migration tools, such as the SAP S/4HANA Migration Cockpit or other conversion tools.
Cause: The error is usually caused by the following scenarios: Number Range Conflicts: The target system may not have the necessary number range intervals defined for the objects being migrated. When the migration tool attempts to assign a number to an object, it finds that the required number range is not available, leading to the creation of a new interval.
Configuration Issues: The number range configuration in the target system may not match the source system, leading to discrepancies during the migration process. Data Consistency: The data being migrated may have gaps or inconsistencies that require the creation of new number ranges to maintain data integrity.
