Message text: NR interval &1: unable to define interval limits due to ambiguity
The system cannot determine the target interval limits automatically.
The program generates number range interval mappings on basis of
existing subobject mappings. If a number range interval exists in a
source subobject but does not exist in a target one, the program creates
a corresponding interval in the target subobject and determines its
limits automatically. However, this determination is not possible if
there are several source subobjects that have the same interval with
different number limits.
Example:
Subobject mapping (company codes):
A001 -> A002
A002 -> A002 (priority company code)
A003 -> A002
Number range intervals (interval 01/2010 does not exist in company code
A002):
RF_BELEG,,A001,,01,,2010,,1000000000,,1999999999
RF_BELEG,,A003,,01,,2010,,2000000000,,2999999999
The program cannot define number range interval limits of the target
interval A002/01/2010, because it is unclear what variant (A001 or A003)
should be chosen.
Comment: if a target subobject differs from a priority subobject,
determination of target number range intervals is based on a priority
subobject.
You should define number range interval limits later in the activity
'Specify Mapping Values for Number Range Objects'.

Error message extract from SAP system. Copyright SAP SE.
The SAP error message CNV_NCE_BAS102 with the description "NR interval &1: unable to define interval limits due to ambiguity" typically occurs during data conversion processes, particularly when using the SAP Data Migration tools or during the execution of certain conversion programs. This error indicates that there is an issue with defining the limits of a numeric range (NR interval) due to ambiguous or conflicting data.
Cause: Ambiguous Data: The data being processed may contain overlapping or conflicting values that make it impossible for the system to determine clear upper and lower limits for the interval. Incorrect Configuration: There may be misconfigurations in the settings or parameters used for the conversion process. Data Quality Issues: The source data may have inconsistencies, such as missing values, duplicates, or incorrect formats that lead to ambiguity. Custom Code or Enhancements: If there are custom developments or enhancements in the conversion process, they may introduce unexpected behavior.
