- & & & already locked by another transaction ?The SAP error message "5A665: & & & already locked by another transaction" indicates that a particular object (such as a document, record, or data entry) is currently locked by another transaction. This locking mechanism is a part of SAP's concurrency control to ensure data integrity and prevent conflicts when multiple users or processes attempt to access or modify the same data simultaneously.
Cause: Concurrent Access: Another user or process is currently accessing or modifying the same object, leading to a lock. Long-Running Transactions: A transaction that takes a long time to complete may hold a lock for an extended period, preventing others from accessing the same object. Uncommitted Transactions: If a transaction is not properly committed or rolled back, it may leave locks in place. System Errors: Occasionally, system errors or crashes can leave locks in place that need to be cleared.
Solution: Wait and Retry: If the lock is temporary, waiting for a few moments
