• What is the cause and solution for SAP error message CNV_DMC_SIN321 - Purchasing Info record &1 already exists for &2 &3 &4 ?

  The SAP error message CNV_DMC_SIN321 indicates that there is an attempt to create a Purchasing Info Record (PIR) that already exists in the system. This error typically arises during data migration or data transfer processes, particularly when using the SAP Data Migration Cockpit or similar tools.
  Cause:
  The error occurs because:
  
  The Purchasing Info Record you are trying to create already exists in the system for the specified vendor and material combination.
  There may be duplicate entries in the source data being migrated.
  The migration process is not correctly handling existing records, leading to conflicts.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Records:
  
  Use transaction code ME11 (Create Purchasing Info Record) or ME12 (Change Purchasing Info Record) to check if the PIR already exists for the specified vendor and material combination.
  If it exists, you may need to update the existing record instead of creating a new one.
  
  
  
  Data Cleansing:
  
  Review the source data for duplicates. Ensure that the data being migrated does not contain multiple entries for the same vendor and material combination.
  Cleanse the data to remove duplicates or consolidate records as necessary.
  
  
  
  Adjust Migration Logic:
  
  If you are using a migration tool, check the mapping and transformation logic to ensure it correctly handles existing records.
  Modify the migration process to skip the creation of records that already exist or to update them instead.
  
  
  
  Error Handling:
  
  Implement error handling in your migration process to log and manage such conflicts effectively. This can help in identifying and resolving issues without halting the entire migration.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific migration tool you are using for any additional guidance or best practices.
