Execution ignores batch node start time and executes a batch with start time in the future (Q805)

The information in this article applies to: 
SIMCA-online 13.1
SIMCA-online 13
Symptoms: 

If a batch id exists in the batch node and has a start time in the future, the SIMCA-online versions listed above fail to respect this start time and will start the real-time (normal) execution as soon as that batch id is found in the process data (as long as phase conditions are fulfilled).

Cause: 

The execution logic was incorrect in regards to this.

Resolution: 

Fixed in SIMCA-online 13.2.

Workaround: 

Avoid prepopulating the batch node too early. Improve the phase conditions so that those prevent the batch from starting prematurely.

More Information: 
Only real-time (normal) execution of the configuration behaves as described above. Repredict execution always respect the batch start and end times of the batch node.
