System error occurred during lock management

Message no. MC600

Diagnosis

An internal error was found in the SAP lock management system when attempting to lock an object by calling an ENQUEUE function module.

System Response

The SAP system cannot enter the required lock correctly into the lock table managed in the ENQUEUE server and the ENQUEUE function module therefore triggers an exception.
If the application cannot process this exception, the active transaction is automatically cancelled.
