• What is the cause and solution for SAP error message CNV_CMIS_M_10084 - Objects already exist. ?

  The SAP error message CNV_CMIS_M_10084: Objects already exist typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools. This error indicates that the system has detected that the objects (such as master data, transactional data, or configuration settings) you are trying to create or migrate already exist in the target system.
  Causes:
  
  Duplicate Data: The most common cause is that the data you are trying to import already exists in the target system. This could be due to previous migration attempts or existing data in the system.
  Incorrect Mapping: If the mapping of source data to target objects is not correctly defined, it may lead to attempts to create objects that already exist.
  Data Consistency Issues: There may be inconsistencies in the data being migrated, leading to conflicts with existing records.
  Migration Process Errors: Errors in the migration process or configuration settings can also lead to this issue.
  
  Solutions:
  
  Check Existing Data: Before running the migration, check the target system for existing records that may conflict with the data you are trying to import. You can use transaction codes like SE16 or SE11 to query the relevant tables.
  Adjust Migration Data: If duplicates are found, you may need to adjust your migration data to either exclude existing records or update them instead of creating new ones.
  Modify Mapping: Review and modify the mapping configuration to ensure that it correctly reflects the relationships between source and target objects.
  Use Update Instead of Create: If the intention is to update existing records, ensure that the migration tool is configured to perform updates rather than create new entries.
  Log Analysis: Review the migration logs for more detailed information about which specific objects are causing the conflict. This can help you identify and resolve the issue more effectively.
  Consult Documentation: Refer to the SAP documentation for the specific migration tool you are using, as it may provide additional insights or troubleshooting steps.

  Data Cleansing: Consider performing data cleansing on the source data before migration to minimize the chances of encountering duplicate records.
