I have to enhance a SAP standard Webdynpro application which is on Floor Plan Manager with additional views. I am able to add additional tabs in the application using the FPM configuration. I have created a Z WD application with 2 views. I am able to display the views inside tabs. How will I share data from component controller between these 2 applications? The obvious answer is making an interface method. But as soon as I enter into enhancement mode and create a method the check box for interface method is taken away i.e. I cannot make this method or any other method as interface method. Any inputs are appreciated.
