Adding new fields on a Redwood page using VB Studio

Summary:

Customer needs to have the Cost Center associated to a Department. An EFF is created to store the value. They are also checking for a way to store/show the cost center based on a field change event. ie based on the department. If this is possible please share your insights.

Redwood page navigation —> employment-change/update/assignment

Below are some other observations I had:-

1. Change assignment is a fragment. So while accessing the fragment it is expecting a listOfSteps array , which I am not able to pass.
2. I have also tried adding one field in the Assignment Layout but that was not getting reflected.
