Bala,
As far as I know, transaction Wizards as the name implies is for Transactions. You can have next or previous provided you are in the same transaction context and have multiple screens under your screenset that you defined for your transaction.
There is a misconception on next and previous when it comes to "Actions" and the multiple steps.
Example: Action 1.
Action 1:
Step 1 - Transaction Screenset (screen 1, screen 2, screen 3)
Step 2 - Apply
Step 3 - SubAction (points to another screen)
Step 4 - Apply
This is a transaction wizard next and previous buttons. In step 1, within the multiple transaction screen inside the same screenset you will have next and previous.
In Step 3 where you are inside another screen you cannot have a previous button that goes back to Step 1 as it is already been applied.
So in theory, the previous screen only works inside a transaction and not across multiple steps as described above. Hence it is called Transaction Wizard and not Action Wizard.
In your picture above you have looping that runs on all displayed items and to run 1 action RecordPointWrapper. From my definition above it will not know how to go back to your previously saved (applied) action.
There is a different button < and > that goes down the looping on the displayed list. There is something about apply that you cannot unapply it.
Hope this helps clear the definition.
