How do I fetch value after I accept a task?

Question

I am creating a vehicle rental application. I wanted to change the rental status of the application after the supervisor accepts the task 
 
 Here in this process model, how do I get the value after supervisor (supervisor change status node) accepts a task. I want to use write records to change the value of rental status to false. 
 Could someone help me with this.

I typically do such things using a bunch of a!save() calls in the saveInto parameter of the submit button. The other option is to add a script task before the "Write Records" node to adjust your values.
