• What is the cause and solution for SAP error message CNV_20900037 - Automatic renaming by NRIV changes is not possible for merge ?

  The SAP error message CNV_20900037 indicates that there is an issue with automatic renaming of number ranges during a merge operation in the context of data migration or conversion. This error typically arises in scenarios where you are using the SAP S/4HANA Migration Cockpit or other data migration tools that involve merging data from different sources or systems.
  Cause:
  The error occurs when the system attempts to automatically rename number ranges (NRIV) during a merge operation, but it is unable to do so. This can happen due to several reasons, including:
  
  Conflicting Number Ranges: There may be overlapping or conflicting number ranges between the source systems that are being merged.
  Configuration Issues: The number range configuration may not be set up correctly in the target system.
  Data Integrity Constraints: There may be constraints in the data that prevent the renaming of number ranges, such as existing records that would conflict with the new number ranges.
  Authorization Issues: The user executing the merge may not have the necessary authorizations to perform the renaming of number ranges.
  
  Solution:
  To resolve the error CNV_20900037, you can take the following steps:
  
  
  Check Number Range Configuration:
  
  Review the number range settings in both the source and target systems to identify any conflicts.
  Ensure that the number ranges are properly defined and do not overlap.
  
  
  
  Manual Renaming:
  
  If automatic renaming is not possible, consider manually renaming the number ranges in the target system before performing the merge.
  Use transaction code SNRO to manage number ranges and ensure they are unique.
  
  
  
  Data Cleanup:
  
  Check for any existing records that may conflict with the new number ranges and clean up the data if necessary.
  Ensure that there are no data integrity issues that could prevent the renaming process.
  
  
  
  Authorization Check:
  
  Verify that the user executing the merge has the necessary authorizations to modify number ranges.
  If needed, consult with your SAP security team to ensure proper access rights.
