Hi Anish,
The process will be associated(trigger on creat) with any table.
for starting the debugging you will need to make sure you are saving the data in the same table from the form submit button.
And try after refreshing dependency for all related modules. 

Hello ,

You can add Breakpoints  in Process flow  and start debug processes .

Also you can check Process log in Service center in Monitoring tab - Process log .

Regards, 

Anuli. 

Hi Anish,
We experienced the same situation before, we were able to add the breakpoint but we were not able to start the debugging.
The workaround we used is to add the LogMessage action across the flow and check the General Log tab in Service Center.
