Reg process start form

insted of a!startprocess() use a!startProcessLink() to see interface in another process model which is chained or start form.

https://docs.appian.com/suite/help/19.4/Ways_to_Start_a_Process_From_a_Process.html#starting-a-process-from-an-interface

so in the main interface i am calling this process model by (a!startprocesslink) now after this process model is ended it has to return the main interface 

it has to get the process veriables to that main interface 

is it possible

what type of process variables ,are you saving these process variables in data base in startprocesslink process model ?

no i am note saving those Process veriables into Data Base 

For this you should probably not be using a!startProcessLink, but instead, have the button be a normal submit button, and upon exiting the form, have the process take a specific flow (via an XOR node checking for which button was pressed), to enter a subprocess where you then use the process you were starting via a!startProcessLink.  In this way, you'll be able to both preserver user inputs on the original form, as well as carry back data from the subprocess, as needed.  There really is no easy way to do this using your current setup.
