Hi Pallavi,
You have two options:
1. Redefine I-getter for all the fields which you want to make read-only - This is high on efforts and poor design for maintainance
2.
a. Create additional view configuration (for read only mode) per view
b. Redefine DO_CONFIG_DETERMINATION of view controller and set the view configuration based on the status - you will have to do this for all the views
