SAP Error Message - Details

• Message type: E = Error

• Message class: RA - Monitoring structure dialog message

• Message number: 504

• Message text: Unable to add MTEs to CCMS alert monitor

What causes this issue?

The CCMS monitoring architecture does not have enough storage to create
a new monitoring tree element. The function module call that creates
the MTE failed.

System Response

Not all MTEs in the affected monitor tree in the alert monitor (RZ20)
could be created. One or more MTEs is missing from the display and
from the underlying CCMS Monitoring Architecture infrastructure.

How to fix this error?

In transaction RZ20, open the monitoring collection 'SAP CCMS Technical
Expert Monitors' . Open one of the self-monitoring monitors and look
for the 'Space' MTE.. The analysis tool for Space shows whether there
are problems in each of the shared memory areas (one per application
server) that the monitoring architecture is using. It also shows how
to correct the problem - by increasing the size of the shared memory
area and restarting each affected application server.
