• What is the cause and solution for SAP error message ML4HRUN123 - Keys of Modified and Original Record of Row Index &1 are different ?

  The SAP error message ML4HRUN123 indicates that there is a mismatch between the keys of the modified record and the original record in a specific row index. This typically occurs during operations that involve data updates or modifications, such as during the execution of a report or transaction that processes data in the Material Management (MM) or Human Resources (HR) modules.
  Cause:
  The error is usually caused by one of the following reasons:
  
  Data Inconsistency: The original record has been changed or deleted after it was read into the program, leading to a mismatch when the program attempts to update it.
  Concurrency Issues: Multiple users or processes may be trying to modify the same record simultaneously, causing conflicts.
  Incorrect Key Mapping: The keys used to identify the records may not match due to incorrect data handling or processing logic in the program.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Data Consistency:
  
  Verify that the original record still exists in the database and has not been modified or deleted by another process.
  Ensure that the data being processed is consistent and valid.
  
  
  
  Review the Program Logic:
  
  If you are developing or maintaining a custom program, review the logic that handles the data updates. Ensure that the keys are being correctly mapped and that the original record is being fetched correctly before any modifications are made.
  
  
  
  Handle Concurrency:
  
  Implement proper locking mechanisms to prevent concurrent modifications of the same record. This can include using database locks or application-level locks.
  
  
  
  Debugging:
  
  If you have access to debugging tools, you can set breakpoints in the program to inspect the values of the keys and the records being processed. This can help identify where the mismatch is occurring.
  
  
  
  Consult Documentation:
  
  Check SAP documentation or notes related to the specific transaction or report you are using. There may be known issues or patches available that address this error.
