ABAP Lock Objects

An ABAP Lock Object is a repository object that a developer defines to coordinate concurrent access to shared data in an SAP system. It enables controlled locking and unlocking of database records by generating corresponding enqueue and dequeue function modules, which can be called to set locks (ENQUEUE_) and release locks (DEQUEUE_). Developers use lock objects to prevent data inconsistencies that can arise when multiple users or processes attempt to read or modify the same records simultaneously.
