• What is the cause and solution for SAP error message CK187 - System error when locking ?

  The SAP error message CK187 ("System error when locking") typically occurs in the context of the Controlling (CO) module, particularly during processes that involve material valuation or cost calculations. This error indicates that there is a problem with the system's ability to lock certain resources or data during a transaction, which can lead to inconsistencies or data integrity issues.
  Causes:
  
  Database Lock Issues: The error may arise due to issues with database locks, where the system is unable to acquire a lock on a required resource because it is already locked by another process or user.
  System Performance: High system load or performance issues can lead to timeouts or failures in acquiring locks.
  Configuration Issues: Incorrect configuration in the system settings related to locking mechanisms can also lead to this error.
  Transport Issues: If there are ongoing transports or changes being made to the system, it may cause temporary locking issues.
  User Authorizations: Insufficient user authorizations to perform the locking operation can also trigger this error.
  
  Solutions:
  
  Check Lock Entries: Use transaction code SM12 to check for existing lock entries. If you find locks that are no longer needed, you can delete them (ensure that you have the necessary authorizations to do so).
  System Performance Monitoring: Monitor system performance and check for any long-running processes that may be holding locks. You can use transaction SM66 to view active processes.
  Review Configuration: Ensure that the configuration settings related to locking mechanisms are correctly set up. Consult with your SAP Basis team if necessary.
  User Authorizations: Verify that the user has the necessary authorizations to perform the operation that is causing the error.
  Restart the Transaction: Sometimes, simply restarting the transaction or logging out and back into the system can resolve temporary locking issues.
  Check for Ongoing Transports: If there are ongoing transports, wait for them to complete before retrying the operation.
