• What is the cause and solution for SAP error message CNV20410051 - Source Op.conc. &1: Different mapping for target fields &2 and &3 ?

  The SAP error message CNV20410051 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 a conflict in the mapping of source fields to target fields in the data transformation process.
  Cause:
  The error message "Source Op.conc. &1: Different mapping for target fields &2 and &3" suggests that the system has detected that the same source field (indicated by &1) is being mapped to two different target fields (indicated by &2 and &3). This can happen due to:
  
  Inconsistent Mapping: The mapping configuration for the data migration is inconsistent, where the same source field is incorrectly assigned to multiple target fields.
  Data Model Changes: Changes in the data model between the source and target systems may lead to conflicts in how fields are mapped.
  Configuration Errors: Errors in the configuration of the migration project, such as incorrect settings in the mapping tables or transformation rules.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Review Mapping Configuration:
  
  Check the mapping configuration in the migration tool. Ensure that each source field is mapped to a unique target field.
  Look for any duplicate mappings or incorrect assignments.
  
  
  
  Adjust Mapping Rules:
  
  If the same source field needs to be mapped to different target fields based on certain conditions, consider creating separate transformation rules or logic to handle these cases.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation for the specific migration tool you are using. There may be guidelines or best practices for setting up mappings correctly.
  
  
  
  Test with Sample Data:
  
  Before running the full migration, test the mapping with a small set of sample data to ensure that the mappings are working as expected.
  
  
  
  Seek Help from SAP Support:
  
  If you are unable to resolve the issue, consider reaching out to SAP support or consulting with an SAP expert who can provide guidance based on your specific scenario.
  
  
  
  Related Information:
  
  Migration Cockpit: This is a tool provided by SAP for migrating data to S/4HANA. Understanding how to use it effectively can help avoid mapping issues.
  Data Mapping: Familiarize yourself with the data model of both the source and target systems to ensure that mappings are logical and consistent.
  Error Logs: Check the error logs or detailed messages provided by the migration tool for additional context on the error.
  
  By carefully reviewing the mapping configuration and ensuring that each source field is uniquely mapped to a target field, you should be able to resolve the CNV20410051 error.
