Line or Object Action Failed

Symptom:

I receive the following message when attempting to initiate line or object actions:

SYV0044E Object not last to execute or session timed out

Reason:

A line or object action was attempted on an object and the action could not be executed due to one of the following reasons:

The object must be the most recent object retrieved from CA SYSVIEW to ensure that its state has not changed.
The CA SYSVIEW session has timed out and the object state is no longer valid.

Solution:

Refresh the object and try the action again.
