• What is the cause and solution for SAP error message RSM813 - & terminated, as no locking currently possible ?

  The SAP error message RSM813 typically indicates that a process has been terminated because it could not acquire a lock on a resource. This can happen in various scenarios, such as during data processing or when trying to access certain transactions or reports. The message "terminated, as no locking currently possible" suggests that the system is unable to proceed due to a locking issue.
  Causes:
  
  Lock Contention: Multiple processes are trying to access the same resource simultaneously, leading to a situation where one process cannot obtain the necessary lock.
  Long-Running Transactions: If a transaction is taking too long to complete, it may hold locks longer than expected, preventing other processes from acquiring the necessary locks.
  Deadlocks: Two or more processes are waiting for each other to release locks, resulting in a deadlock situation.
  System Configuration Issues: Incorrect configuration of the SAP system or database settings can lead to locking issues.
  Database Issues: Problems with the underlying database, such as performance issues or corruption, can also lead to locking problems.
  
  Solutions:
  
  
  Identify and Resolve Lock Contention:
  
  Use transaction SM12 to check for existing locks. You can see which users or processes are holding locks and release them if necessary.
  If you identify a long-running transaction, consider terminating it if it is safe to do so.
  
  
  
  Monitor and Optimize Long-Running Transactions:
  
  Analyze the performance of transactions that are known to take a long time. Optimize them if possible to reduce the time they hold locks.
  Consider breaking down large transactions into smaller, more manageable ones.
  
  
  
  Check for Deadlocks:
  
  Use transaction SM21 to check the system log for deadlock situations.
  If deadlocks are frequent, analyze the processes involved and consider redesigning them to avoid contention.
  
  
  
  Review System Configuration:
  
  Ensure that the SAP system and database configurations are optimized for performance and locking behavior.
  Consult with your Basis team to review any relevant settings.
  
  
  
  Database Maintenance:
  
  Perform regular database maintenance tasks, such as updating statistics and checking for corruption.
  Ensure that the database is properly tuned for performance.
  
  
  
  SAP Notes and Support:
