How To Fix CNV20201419 - Possible overlap of number ranges: &1, target subobj.=&2

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV20201 -

• Message number: 419

• Message text: Possible overlap of number ranges: &1, target subobj.=&2

What causes this issue?

Possible overlap of number ranges (assuming that the shifting rule is
used:
&V1&, target subobject = &V2&
Number range 1 (source subobj./NoRgNo/MinNo(new)/MaxNo(new) =
&V3&
Number range 2 (source subobj./NoRgNo/MinNo(new)/MaxNo(new) =
&V4&
The interval that is created by the new min. no. and the new max. no.
overlaps with the interval of another number range.
As a rule, different number ranges must have disjoint number intervals.
NoRgNo: 2-digit number range number
Min-Nr: From-number of the interval
Max-Nr: highest assigned number in the interval

• What is the cause and solution for SAP error message CNV20201419 - Possible overlap of number ranges: &1, target subobj.=&2 ?

  The SAP error message CNV20201419 indicates a potential overlap of number ranges during a data migration or conversion process. This error typically arises when there are conflicting number ranges for the same object in the source and target systems, which can lead to data integrity issues.
  Cause:
  
  Overlapping Number Ranges: The error occurs when the number ranges defined for a specific object (e.g., customer numbers, material numbers) in the target system overlap with those in the source system.
  Configuration Issues: Incorrect configuration of number ranges in the target system can lead to this overlap.
  Data Migration Process: During data migration, if the same number range is being used for different objects or if the ranges are not properly defined, this error can occur.
  
  Solution:
  
  Check Number Ranges: Review the number ranges defined in both the source and target systems for the specified object. Ensure that there are no overlaps.
  Adjust Number Ranges: If overlaps are found, adjust the number ranges in the target system to ensure they are unique and do not conflict with those in the source system.
  Use Different Ranges: If necessary, create new number ranges in the target system that do not overlap with existing ones.
  Consult Documentation: Refer to SAP documentation or guides related to number range configuration to ensure proper setup.
  Testing: After making adjustments, perform a test migration to verify that the error has been resolved.
  
  Related Information:
  
  Transaction Codes: You can use transaction codes like SNRO (Number Range Objects) to manage and configure number ranges in SAP.
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or solutions related to this error.
  Data Migration Tools: If you are using specific data migration tools (like SAP S/4HANA Migration Cockpit), refer to their documentation for best practices regarding number range management.
  Support: If the issue persists, consider reaching out to SAP support or consulting with an SAP expert for further assistance.
  
  By addressing the number range configuration and ensuring there are no overlaps, you should be able to resolve the CNV20201419 error.
