• What is the cause and solution for SAP error message CNV20600017 - Temporary duplicates will occur as a result of this mapping ?

  The SAP error message CNV20600017 indicates that temporary duplicates will occur due to the mapping configuration in a data migration or conversion process. This error is typically encountered during the execution of a data migration project, especially when using SAP's data migration tools, such as the SAP S/4HANA Migration Cockpit or other conversion tools.
  Cause:
  The error arises when the mapping rules defined for the data migration lead to the creation of duplicate entries in the target system. This can happen due to several reasons, including:
  
  Mapping Configuration: The mapping rules may not be correctly defined, leading to multiple source records being mapped to the same target record.
  Data Quality Issues: The source data may contain duplicates or inconsistencies that are not being handled properly during the mapping process.
  Key Field Conflicts: If the key fields in the target system are not unique or if the mapping does not ensure uniqueness, it can lead to temporary duplicates.
  
  Solution:
  To resolve the CNV20600017 error, you can take the following steps:
  
  
  Review Mapping Rules: Check the mapping configuration to ensure that it correctly defines how source records are mapped to target records. Ensure that each source record maps to a unique target record.
  
  
  Data Cleansing: Perform data cleansing on the source data to eliminate duplicates or inconsistencies before the migration. This may involve deduplication processes or data validation checks.
  
  
  Adjust Key Fields: Ensure that the key fields in the target system are set up to maintain uniqueness. If necessary, modify the mapping to include additional fields that can help create a unique identifier for each record.
  
  
  Test Migration: Conduct a test migration with a smaller dataset to identify potential issues before performing the full migration. This can help you catch and resolve mapping issues early.
  
  
  Consult Documentation: Refer to SAP documentation or guides related to the specific migration tool you are using. There may be specific recommendations or best practices for handling duplicates.
  
  
  Seek Support: If the issue persists, consider reaching out to SAP support or consulting with an SAP expert who can provide insights based on your specific scenario.
