• What is the cause and solution for SAP error message 62923 - RE key exists several times (Data inconsistency) ?

  The SAP error message 62923, which states "RE key exists several times (Data inconsistency)," typically indicates that there is a data inconsistency issue in the system. This error occurs when the system detects that a key (usually a unique identifier for a record) is duplicated in a table where it should be unique. This can happen in various contexts, such as during data entry, data migration, or when running certain transactions.
  Causes:
  
  Data Duplication: The most common cause is that the same key has been entered multiple times in the database, violating the uniqueness constraint.
  Data Migration Issues: If data has been migrated from another system or from legacy data, it may not have been cleaned properly, leading to duplicates.
  Concurrent Transactions: If multiple users or processes are trying to create or update records simultaneously, it may lead to race conditions that result in duplicate keys.
  Incorrect Configuration: Sometimes, configuration settings in the system may allow for duplicate entries when they should not.
  
  Solutions:
  
  Identify Duplicates: Use SQL queries or SAP transaction codes (like SE16 or SE11) to identify the records that have duplicate keys. You can check the relevant database table for duplicates.
  
  Example SQL query:
  SELECT key_field, COUNT(*)
  FROM your_table
  GROUP BY key_field
  HAVING COUNT(*) > 1;
  
  
  
  Data Cleanup: Once duplicates are identified, you will need to decide how to handle them. This may involve:
  
  Deleting the duplicate records.
  Merging records if they contain different information.
  Correcting the data entry process to prevent future duplicates.
  
  
  Check Data Migration Processes: If the issue arose from a data migration, review the migration scripts or processes to ensure they include checks for duplicates.
  Review Configuration: Check the configuration settings in the relevant modules to ensure that they are set up to prevent duplicate entries.
  Consult SAP Notes: Look for any relevant SAP Notes that may address this specific error or provide guidance on handling data inconsistencies.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like SE16 (Data Browser), SE11 (Data Dictionary), and SE78 (SAP ArchiveLink) to investigate the data.
  SAP Support: If the issue persists or is complex, consider reaching out to SAP support for assistance.
  Documentation: Review SAP documentation related to the specific module or area where the error occurred, as it may provide additional insights or troubleshooting steps.
