Using Call, SetContext functions in Process Flow

Example:

Parent Flow: ATMTransaction
Child Process Flow: TransactionConfirmation

Objective:
- How Call function can be used to call sub-processes (i.e., child flows)?
- How context variables can be passed from Parent to Child flows
(and vice versa)?

Pass an ATM Card Number to sub-process via a Call function. Sub-process
Receives the ATM Card number from the Parent flow and stores it in a file.

Sub-process then sends back a “data” response to Parent flow. Parent flow
receives the response and stores it in a file.

This example uses SetChildContext, SetParentContext, ContextSource, Call functions.
