• What is the cause and solution for SAP error message CNV_20900081 - There are temporary duplicates for vendor numbers ?

  The SAP error message CNV_20900081 indicates that there are temporary duplicates for vendor numbers during a data migration or conversion process. This error typically arises in the context of using SAP's data migration tools, such as the SAP S/4HANA Migration Cockpit or other data transfer methods.
  Cause:
  The error occurs when the system detects that there are multiple entries for the same vendor number in the source data. This can happen due to:
  
  Data Duplication: The source data may contain duplicate vendor records, which can occur due to data entry errors or issues during data extraction from legacy systems.
  Temporary Vendor Numbers: The system may have temporary vendor numbers that are not yet finalized or are in a transitional state.
  Data Format Issues: The vendor numbers may not be formatted consistently, leading the system to interpret them as duplicates.
  
  Solution:
  To resolve the error, you can follow these steps:
  
  
  Identify Duplicates:
  
  Review the source data to identify any duplicate vendor numbers. You can use tools like Excel or SQL queries to find duplicates in your dataset.
  
  
  
  Clean Up Data:
  
  Remove or consolidate duplicate entries. Ensure that each vendor number is unique and corresponds to a single vendor record.
  If there are legitimate reasons for having multiple entries (e.g., different addresses or contact details), consider merging them into a single record.
  
  
  
  Check Temporary Vendor Numbers:
  
  If the duplicates are due to temporary vendor numbers, ensure that these are resolved before the migration. You may need to finalize or deactivate temporary records.
  
  
  
  Reformat Data:
  
  Ensure that the vendor numbers are consistently formatted. Check for leading/trailing spaces, different character sets, or other formatting issues.
  
  
  
  Test Migration:
  
  After cleaning the data, run a test migration to ensure that the error does not occur again.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific migration tool you are using for any additional guidance or best practices.
