• What is the cause and solution for SAP error message CNV20201038 - &1: No master table - NRIV number level is used for offset calculation ?

  The SAP error message CNV20201038 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 is an issue with the NRIV (Number Range Intervals) table, which is used to manage number ranges for various objects in SAP.
  Cause:
  The error message "No master table - NRIV number level is used for offset calculation" suggests that the system is unable to find a master table associated with the number range interval (NRIV) that is being referenced. This can happen due to several reasons:
  
  Missing Master Data: The master data that should be linked to the number range is missing or not properly defined in the system.
  Configuration Issues: The number range configuration may not be set up correctly, leading to the system being unable to determine the appropriate master table.
  Data Migration Issues: During data migration, if the number range intervals are not correctly defined or if there are inconsistencies in the data, this error can occur.
  Custom Development: If there are custom developments or modifications in the system that affect number range handling, it may lead to this error.
  
  Solution:
  To resolve the CNV20201038 error, you can take the following steps:
  
  
  Check Number Range Configuration:
  
  Go to transaction code SNRO (Number Range Objects) and verify the configuration of the number range object that is causing the issue.
  Ensure that the number range intervals are correctly defined and that the associated master data is present.
  
  
  
  Verify Master Data:
  
  Check if the master data that should be linked to the number range is available in the system. If it is missing, you may need to create or upload the necessary master data.
  
  
  
  Review Migration Settings:
  
  If you are using a migration tool, review the settings and mappings to ensure that the number range intervals are correctly configured and that there are no inconsistencies in the data being migrated.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific migration or conversion process you are performing. There may be specific guidelines or prerequisites that need to be followed.
  
  
  
  Check for Custom Code:
  
  If there are any custom developments that interact with number ranges, review the code to ensure it is functioning as expected and not causing conflicts.
