be careful when opening and enabling as it try to add ins as a toolbar to run it. otherwise we can still deactivate the toolbar by going though the macro and run the clear toolbar .

We need to click on the plan Factory for it to run. And there are other fields where we can adjust the capacity.

if you need further information please do inform. will be glad to give and of course suggestion will be most welcome.
