• What is the cause and solution for SAP error message SADA112 - Index access through &1 now locked ?

  The SAP error message SADA112 indicates that an index access through a specified index (denoted by &1) is currently locked. This typically occurs when there is a concurrent process trying to access the same index, which can lead to contention and locking issues.
  Cause:
  
  Concurrent Access: Multiple transactions or processes are trying to access or modify the same index simultaneously.
  Long-running Transactions: A transaction that takes a long time to complete may hold a lock on the index, preventing other transactions from accessing it.
  Database Locking Mechanism: The underlying database may have a locking mechanism that prevents access to the index while it is being modified or accessed by another transaction.
  
  Solution:
  
  Identify the Lock: Use transaction codes like SM12 (for lock entries) to identify which user or process is holding the lock on the index.
  Wait and Retry: If the lock is temporary, you may simply wait for the other transaction to complete and then retry your operation.
  Terminate the Lock: If you determine that the lock is held by a long-running or stuck transaction, you may need to terminate that transaction. This can be done using transaction SM50 (for process overview) or SM66 (for global process overview).
  Optimize Transactions: Review the transactions that are causing locks and optimize them to reduce the time they hold locks. This may involve breaking them into smaller transactions or improving performance.
  Database Configuration: Check the database configuration for lock settings and consider adjusting them if necessary, but this should be done with caution and ideally with the help of a database administrator.
  
  Related Information:
