• What is the cause and solution for SAP error message CNV_NCE_BAS181 - NR interval &1: initialization of mapping values is required ?

  The SAP error message CNV_NCE_BAS181 with the description "NR interval &1: initialization of mapping values is required" typically occurs during data migration or conversion processes, particularly when using SAP's Data Migration tools or the SAP S/4HANA Migration Cockpit. This error indicates that there is an issue with the mapping of number ranges (NR) during the initialization phase of the data migration.
  Cause:
  
  Uninitialized Mapping Values: The error suggests that the mapping values for a specific number range interval have not been initialized. This can happen if the configuration for the number range mapping is incomplete or if the necessary data has not been set up in the system.
  Missing Configuration: The number range object may not be properly configured in the system, leading to the inability to map the values correctly.
  Data Migration Process: If you are using a migration tool, it may not have the necessary information to proceed with the mapping of number ranges.
  
  Solution:
  
  
  Initialize Mapping Values: 
  
  Go to the relevant transaction or tool where the mapping is configured (e.g., the Migration Cockpit).
  Check the number range mapping settings and ensure that all required intervals are initialized.
  If necessary, manually initialize the mapping values for the specified number range interval.
  
  
  
  Check Number Range Configuration:
  
  Use transaction code SNRO to check the configuration of the number range object related to the error.
  Ensure that the number range intervals are defined and active.
  
  
  
  Review Migration Settings:
  
  If you are using a migration tool, review the settings and ensure that all necessary configurations are in place.
