to check inbuilt flag or functin call when we stop production using DPM dashboard

Hi,
I want to figure out if there are any built in functions or scripts or flags that are being triggered when I stop the ongoing production in DPM Dashboard.
I want to write a script in which when ever we will stop the production I want to change the production count to a static value in the dashboard. So for that I was checking if we could see any services being called or function being called so that I could make appropriate changes.
