• What is the cause and solution for SAP error message NGC_CORE_COMMON010 - Classification data of &1 (&2) is already being processed. ?

  The SAP error message "NGC_CORE_COMMON010: Classification data of &1 (&2) is already being processed" typically indicates that there is a conflict in processing classification data for a specific object in the system. This can occur when multiple processes or transactions are trying to access or modify the same classification data simultaneously.
  Cause:
  
  Concurrent Processing: The most common cause of this error is that another user or process is currently processing the same classification data. This can happen in scenarios where multiple users are trying to update or classify the same object at the same time.
  Locking Mechanism: SAP uses a locking mechanism to prevent data inconsistencies. If a record is locked by one transaction, other transactions trying to access it will receive this error.
  Long-running Transactions: If a transaction takes too long to complete, it may hold the lock for an extended period, causing other transactions to fail with this error.
  
  Solution:
  
  Wait and Retry: If you encounter this error, the simplest solution is to wait for a few moments and then retry the operation. The other process may complete, releasing the lock on the classification data.
  Identify the Lock: Use transaction codes like SM12 (to view and manage locks) to identify which user or process is holding the lock on the classification data. You can then coordinate with that user to resolve the conflict.
  Check for Long-running Processes: If a specific transaction is taking too long, investigate why it is slow. You may need to optimize the process or check for any issues that are causing delays.
  System Monitoring: Implement monitoring tools to keep track of long-running transactions and locks in the system to prevent such issues in the future.
  Consult SAP Notes: Check the SAP Support Portal for any relevant notes or updates related to this error message. There may be specific patches or updates that address known issues.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like SM12 (to view locks), SM21 (to check system logs), and ST22 (to check dumps) for troubleshooting.
  SAP Documentation: Refer to SAP Help documentation for more details on classification data and the locking mechanism.
  User Coordination: If multiple users are frequently accessing the same data, consider implementing a process to coordinate changes to avoid conflicts.
  
  If the problem persists after trying the above solutions, it may be necessary to involve your SAP Basis team or SAP support for further investigation.
