Trigger Smartform from account

Hello Gurus,

I am trying to generate a PDF smartform from the corporate account screen.  I am following an example from a consultant who accomplished this in our activities using actions.  I have already created the event and added the button in viewset BP_HEAD/ACCOUNTVIEWSET.  The attached code attempts to retrieve the smartform from the action for the customer from the webui.  I'm getting an error when trying to set LR_ACTIONCONTEXT.

I'm aware that BTHeaderAction is not defined but I'm not sure how to retrieve the available actions as the consultant did.  Do I need to create a relation?  Is it possible to generate the smartform from an action on the account?

Any tips are greatly appreciated.
