How To Fix CNV_NCE_BAS430 - Cannot skip simulation for overlapping no. range intervals

CNV_NCE_BAS430 - Overview

• Message type: E = Error

• Message class: CNV_NCE_BAS - Number conversion engine: messages

• Message number: 430

• Message text: Cannot skip simulation for overlapping no. range intervals

What causes this issue?

Number range interval ( OBJECT = &V1& / SUBOBJECT = &V2& / NRRANGENR =
&V3& / TOYEAR = &V4& ) overlaps wiith otherr number range intervals. The
activity <ZK>Simulate Number Conversion During System Lock </>is
therefore mandatory.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Ensure that the checkbox <ZK>Skip the Activity Simulate Number
Conversion During System Lock </>in the <ZK>Simulation Settings</> tab
page is not selected for the number range object &V1&.

CNV_NCE_BAS430 - Details

• The SAP error message CNV_NCE_BAS430: Cannot skip simulation for overlapping no. range intervals typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This error indicates that there are overlapping number range intervals defined in the system, which can lead to conflicts during the data migration process.
  
  Cause:
  The error is caused by the presence of overlapping number range intervals in the configuration of the system. Number ranges are used to uniquely identify records in various SAP objects, and if two or more intervals overlap, the system cannot determine which interval to use for new records, leading to ambiguity.
  
  Solution:
  To resolve this error, you need to identify and correct the overlapping number range intervals. Here are the steps to do so:
  
  
  Identify Overlapping Intervals:
  
  Go to the transaction code SNRO (Number Range Objects).
  Find the relevant number range object that is causing the issue.
  Check the defined intervals
