• What is the cause and solution for SAP error message CNV20200365 - For &1 &2, temporary duplicates may occur ?

  The SAP error message CNV20200365 indicates that during a data migration or conversion process, temporary duplicates may occur for the specified objects (indicated by &1 and &2). This message is typically associated with the SAP S/4HANA migration process or data transfer activities where data integrity is crucial.
  Cause:
  The error message CNV20200365 is usually triggered when the data migration process encounters situations where the same data records might be temporarily duplicated. This can happen due to:
  
  Data Overlap: When migrating data from legacy systems, there may be overlapping records that are not uniquely identified.
  Concurrency Issues: If multiple processes are trying to insert or update records simultaneously, it can lead to temporary duplicates.
  Data Transformation Logic: The logic used to transform data from the source to the target system may not adequately handle unique constraints.
  
  Solution:
  To resolve this issue, consider the following steps:
  
  
  Review Data Mapping: Ensure that the data mapping and transformation rules are correctly defined to avoid overlaps. Check for unique identifiers in the source data.
  
  
  Data Cleansing: Before migration, perform data cleansing to remove duplicates or merge records that may cause conflicts.
  
  
  Batch Processing: If possible, process data in smaller batches to minimize the risk of concurrency issues.
  
  
  Locking Mechanisms: Implement locking mechanisms to prevent multiple processes from modifying the same records simultaneously.
  
  
  Post-Migration Validation: After the migration, run validation checks to identify and resolve any duplicates that may have occurred.
  
  
  Consult SAP Notes: Check for any relevant SAP Notes or documentation that may provide additional guidance or patches related to this error.
