How To Fix CNV_NCE_BAS103 - NR interval &1 overlaps with another NR interval

CNV_NCE_BAS103 - Overview

• Message type: E = Error

• Message class: CNV_NCE_BAS - Number conversion engine: messages

• Message number: 103

• Message text: NR interval &1 overlaps with another NR interval

What causes this issue?

The system has determined that two target intervals overlap.

System Response

The system generates number range interval mapping values from existing
subobject mapping values. If a number range interval exists in a source
subobject, but does not exist in a target one, the system creates a
corresponding interval in the target subobject and determines its limits
automatically. This determination has shown that the new number range
interval overlaps with an already existing, or another new number range
interval.
Example:
Subobject mapping values (company codes):
A001 -> A002
A002 -> A002 (priority company code)
Number range intervals (interval 01/2010 does not exist in company code
A002):
RF_BELEG,,A001,,01,,2010,,1000000000,,1999999999
RF_BELEG,,A002,,02,,2010,,1000000000,,1999999999
The system creates a target interval A002/01/2010 according to the
subobject mapping values. The new interval overlaps with the existing
interval A002/02/2010.
Note:
If a target subobject differs from a priority subobject, the
determination of the target number range intervals is based on the
priority subobject.

CNV_NCE_BAS103 - Details

• The SAP error message CNV_NCE_BAS103 indicates that there is an overlap in the number range (NR) intervals defined in the system. This typically occurs during data migration or when configuring number ranges for various objects in SAP. The error message specifically states that the number range interval you are trying to define overlaps with another existing number range interval.
  
  Cause:
  
  
  Overlapping Number Ranges: The primary cause of this error is that the number range you are trying to create or modify overlaps with an existing number range. For example, if you have an existing number range from 1000 to 2000 and you try to create a new number range from 1500 to 2500, this will trigger the error because the ranges overlap.
  
  
  Incorrect Configuration: This can also happen if there are mistakes in the configuration of number ranges, such as incorrect start and end values.
  
  
  Data Migration Issues: During data migration, if the number
