• What is the cause and solution for SAP error message CNV_20600_CHECK160 - No temporary dupl. possible due to mapping of comp.code for no. assignm. ?

  The SAP error message CNV_20600_CHECK160 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 mapping of company codes for number assignment, which prevents the creation of temporary duplicates.
  Cause:
  The error is generally caused by one of the following reasons:
  
  
  Mapping Issues: The mapping of company codes in the migration data does not align correctly with the existing company codes in the target system. This can happen if the source data has company codes that are not defined in the target system.
  
  
  Number Assignment Conflicts: The system is unable to create temporary duplicates because the number assignment for the company codes is not set up correctly. This can occur if the number ranges for the company codes are overlapping or if there are restrictions on number assignments.
  
  
  Configuration Errors: There may be configuration issues in the target system related to number ranges or company code settings that prevent the system from processing the data correctly.
  
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Mapping: Review the mapping of company codes in your migration data. Ensure that all company codes in the source data are correctly mapped to existing company codes in the target system.
  
  
  Verify Number Ranges: Check the number range settings for the company codes involved. Ensure that the number ranges are correctly defined and do not overlap. You can do this by navigating to the relevant configuration settings in SAP.
  
  
  Adjust Configuration: If necessary, adjust the configuration for number assignments in the target system. This may involve creating new number ranges or modifying existing ones to accommodate the incoming data.
  
  
  Test Migration: After making the necessary adjustments, perform a test migration to see if the error persists. Monitor the logs for any additional errors that may arise.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to the specific migration tool you are using for any additional guidance or troubleshooting steps.
  
  
  Seek Support: If the issue persists after trying the above steps, consider reaching out to SAP support or consulting with an SAP expert who can provide more tailored assistance based on your specific scenario.
  
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like OBAS (for number range maintenance) or SPRO (to access the configuration settings) to check and adjust settings.
  SAP Notes: Look for relevant SAP Notes that may address this specific error or provide additional context.
  Migration Cockpit: Familiarize yourself with the SAP S/4HANA Migration Cockpit documentation, as it may provide insights into common issues and best practices for data migration.
