Hi All,
i know that PV is used to carry through out the process and AC within the node.
But, i can't understand which are PV. is it only the rule inputs in interface can be PV or how it is used practically.
and on what purpose we configure input nodes and and when we configure input.
also what is the impact of save into. please answer.

Think of a pv! as a "global variable" available across a process model. It can be used to pass values to/from individual smart services and therefore carry values between smart services. You can also use it as an input value to the process model itself (if set as a 'parameter').
Activity Class variables (ac!) are essentially "private" to individual smart services, and you can pass these values to the smart service implementation e.g. if a User Input Task then the ac! is the value that is made available to a User Interface via the rule input. You can set the value of an ac! from a pv! and you can save the value of an ac! to a pv!
