Which variables are used to pass data into and out of a subprocess?

• A. Input and Output variables
• B. Local and Global variables
• C. pv! and rv!
• D. Process variables only

Answer: (A)

Data is passed into and out of a subprocess using input and output parameters. In Appian, the subprocess defines a set of input parameters to receive values from the calling process and a set of output parameters to return values when the subprocess completes. You map the parent process variables to the subprocess’s inputs when you configure the subprocess, and then map the subprocess’s outputs back to variables in the parent to capture results. This explicit parameter passing is what enables data flow across the subprocess boundary. Other variable types or referencing process variables directly inside the subprocess do not establish this cross-process data channel in the same structured way.
