Hi Again
I believe I know the cause of the issue.
You are trying to schedule the Maintenance Plan with a start time which is later earlier than your first entries for the counters.
So for example in your case, you are trying to run the plan to start with date 16.4 with time 11:10 in which there were not any measurement document generated yet.
So either enter some measurement readings earlier or better you start your plan later...
And that seems not related with TECO.
