Message type: E = Error
Message class: PAB - JIT calls
Message number: 028
Message text: Data cannot be blocked (system error)
In trying to lock an object for processing, an internal error was
detected in the SAP lock management.
The SAP system cannot enter the selected lock in the so-called lock
table administered by the ENQUEUE server. Therefore the ENQUEUE
function module sets an exception.
The most common reason for the existing error message is that the
ENQUEUE server can no longer be used. The cause for this can be that
either the ENQUEUE server itself or the message server, which forms the
link between application servers and ENQUEUE servers, is no longer
running.
Enquire about the appropriate servers in your system administration.
The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
