• What is the cause and solution for SAP error message 1G618 - Table &1 locked by &2 ?

  The SAP error message 1G618 indicates that a specific table (denoted as &1) is locked by a user or process (denoted as &2). This typically occurs when a transaction is trying to access a table that is currently being modified or accessed by another user or process, leading to a lock situation.
  Cause:
  
  Concurrent Access: Another user or process is currently accessing or modifying the table, which prevents your transaction from obtaining the necessary lock.
  Long-running Transactions: A transaction that takes a long time to complete may hold a lock on the table longer than expected.
  Deadlocks: In some cases, a deadlock situation may arise where two or more processes are waiting for each other to release locks.
  Background Jobs: Background jobs or batch processes may also hold locks on tables, causing conflicts with user transactions.
  
  Solution:
  
  Wait and Retry: If the lock is temporary, waiting for a few moments and then retrying the operation may resolve the issue.
  Identify the Lock: Use transaction codes like SM12 (for lock entries) to identify which user or process is holding the lock on the table. You can check the lock entries and see if you can contact the user or process to release the lock.
  Terminate the Lock: If you have the necessary authorizations, you can delete the lock entry in SM12. However, this should be done with caution, as it may lead to data inconsistencies if the other process is still running.
  Optimize Transactions: Review the transactions that are causing locks and optimize them to reduce the time they hold locks on the table.
  Check for Background Jobs: If a background job is causing the lock, you may need to wait for it to complete or check if it can be rescheduled.
  Consult Basis Team: If the issue persists, it may be necessary to involve your SAP Basis team to investigate further, especially if it involves system performance or configuration issues.
