Techopedia Explains Lock Object
The lock mechanism provided by SAP comes in three types: Read Lock: Allows other methods/transactions to access the object through a read mechanism but cannot modify the locked areas of the object Write Lock: Protection provided to write access of the object. It does not allow any other method/transaction to read or write the locked features of the object. Enhanced Write Lock: Works almost like the write lock although the difference is that it provides additional protection from further access through the same method/transaction.When a lock object is created in SAP, it automatically creates two function modules. These are: ENQUEUE_name of lock object: This function module is used while inserting an object in the queue DEQUEUE_name of the lock object: This function module is used while removing the object from the queue.Advertisement
