Some internal issues may be used log time on, other to plan time on.
At a certain point in time, a "planning" issue may be closed. In that case, one should no longer be able to add planned time for that issue.
In Server/DC, this can be done via Workflow Properties (jira.issue.editable=false).
This is the same suggestion, but for Cloud.
