How To Fix CNV_NCE_BAS204 - Temporary interval &1: target numbers fall into NR interval &2

CNV_NCE_BAS204 - Overview

• Message type: E = Error

• Message class: CNV_NCE_BAS - Number conversion engine: messages

• Message number: 204

• Message text: Temporary interval &1: target numbers fall into NR interval &2

What causes this issue?

The target numbers of the temporary number interval &V1& will lie in the
number range interval &V2& after the conversion.

System Response

The number range interval &V1& contains numbers that do not belong to
any number range intervals that are defined in table NRIV. This interval
is also not mapped to any defined number range interval (the target
number range number is empty). However, its target numbers lie in the
defined number range interval &V2& due to a specified mapping values.

How to fix this error?

Check the numbers that belong to a temporary number interval (you can do
it by selecting the interval and choosing the pushbutton <ZK>Interval
Details</>). Change the mapping values if you do not want them to be
part of any defined interval.
&ADDITIONAL_HINTS&
The system will take these numbers into account while adjusting the
number levels of the number range intervals after conversion.
Example:
Subobject mapping (company codes):
A001 -> A002
A002 -> A002 (priority company code)
Number range intervals (table NRIV) before conversion:
OBJECT,,SUBOBJECT,,NRRANGENR,,TOYEAR,,FROMNUMBER,,TONUMBER,,,,NRLEVEL
RF_BELEG,,A001,,,,,,01,,,,,,2010,,,,1000000000,,,,1999999999,,,,
1000050000
RF_BELEG,,A001,,,,,,02,,,,,,2010,,,,3000000000,,,,3999999999,,,,
3000098906
RF_BELEG,,A002,,,,,,01,,,,,,2010,,,,2000000000,,,,2999999999,,,,
2000070000
There exists a document 2200023255 in the year 2010, company code A001.
This document does not belong to any defined number range intervals. It
lies in a gap between number range intervals A001/01/2010 and
A001/02/2010. The system creates a temporary number interval with limits
that correspond to the gap between the defined number range intervals:
OBJECT,,SUBOBJECT,,NRRANGENR,,TOYEAR,,FROMNUMBER,,TONUMBER,,,,NRLEVEL
RF_BELEG,,A001,,,,,,,,,,,,2010,,,,2000000000,,,,2999999999,,,,2200023255
The conversion rule 'Shifting mode' is used for the intervals
A001/01/2010 and A002/01/2010, and the temporary interval above is
excluded from the conversion with a rule 'No change'. In this case, all
numbers from the interval A001/01/2010 (1000000000-1000050000) will be
moved to the interval A002/01/2010 directly after the number 2000070000.
The number level of the interval A002/01/2010 will increase to the
2000120001. However, number 2200023255 will also fall into the interval
A002/01/2010. The system will set number level of the interval
A002/01/2010 to 2200023255.
Number range intervals (table NRIV) after the conversion:

CNV_NCE_BAS204 - Details

• The SAP error message CNV_NCE_BAS204 typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools. This error indicates that there is a mismatch between the target number range and the source number range during the data transfer process.
  
  Cause:
  The error message "Temporary interval &1: target numbers fall into NR interval &2" suggests that the numbers being transferred from the source system fall into a number range that is not valid or not defined in the target system. This can happen due to several reasons:
  
  Number Range Configuration: The target system may not have the appropriate number range defined for the object being migrated.
  Data Overlap: The data being migrated may contain values that overlap with existing values in the target system's number range.
  Incorrect Mapping: The mapping of number ranges between the source and target systems may not be correctly configured.
