• What is the cause and solution for SAP error message CNV_CMIS_M_10071 - Changes for tables and fields: ?

  The SAP error message CNV_CMIS_M_10071 typically relates to issues encountered during the data migration process, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools. This error indicates that there are changes in the structure of tables or fields that are not compatible with the migration process.
  Cause:
  
  Inconsistent Data Model: The error may arise if there are changes in the data model, such as modifications to table structures or field definitions that are not reflected in the migration settings.
  Missing or Incorrect Mapping: If the mapping between source and target fields is not correctly defined, it can lead to this error.
  Data Type Mismatches: Differences in data types between the source and target systems can also trigger this error.
  Custom Fields: If there are custom fields in the source system that do not exist in the target system, this can lead to issues during migration.
  
  Solution:
  
  Check Data Model Changes: Review the data model in both the source and target systems to ensure that all changes are accounted for. Make sure that the migration settings reflect the current structure.
  Review Mapping Configuration: Go through the mapping configuration in the migration cockpit to ensure that all fields are correctly mapped and that there are no missing mappings.
  Data Type Validation: Validate that the data types of the fields in the source system match those in the target system. If there are discrepancies, you may need to adjust the data types or transform the data accordingly.
  Custom Fields Handling: If there are custom fields in the source system, ensure that they are either mapped to existing fields in the target system or handled appropriately (e.g., by creating corresponding fields in the target system).
  Consult Documentation: Refer to the SAP documentation for the specific migration tool you are using. There may be specific guidelines or best practices for handling changes in tables and fields.
  Testing: Conduct thorough testing of the migration process in a sandbox or development environment before executing it in production. This can help identify and resolve issues without impacting live data.
