CNV_20900037 - Details

• 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.
