Enqueue server down
Diagnosis : An internal error was found in the SAP lock management system when attempting to lock an object by calling an ENQUEUE functionmodule.
System Response
The SAP system cannot enter the required lock correctly into the lock table managed in the ENQUEUE server and the ENQUEUE functionmodule therefore triggers an exception.
If the application cannot process this excepton, the active transaction is automatically cancelled. Procedure
The most common cause of this error message is that it is no longer possible to access the ENQUEUE server. The cause of this may be thateither the ENQUEUE server itself or the message server which establishes the connection between the application server and the ENQUEUEserver in a local system, is no longer running.
The source SAPMSYST is protected. See explanation in long text
Message no. ED800
Diagnosis
The desired source text is protected by SAP because changing it could cause system errors.Utility metadata table: T*DIR
