Component development with Web Dynpro

[Former Member]

Hello,

We would like to offer our customers Web Dynpro components based on RFCs to simplify the development of customer components.

But how can we do it? We can offer Web Dynpro components with context based on our data model (simplified data model), component methods with mapping context <-> rfc. RFCs will provide checks and in success case will update the state of backend (entire data model). Interface of RFCs is based also on simplified data model (structures and internal tables). Views are offered as Windows, as it is not possible to use view in extern component. The customer will map provided context and use Windows and methods to build own components. Customer components will be complex applications with many views.

Customer want of cause to define append fields (in backend data model, in RFC interface and in Web Dynpro Context) and use it in own views. But it is not possible to create new attributes in mapped context. I can use enchancement framework, but i am not sure if it is a correct way.

Maybe there are some references to solutions for similar tasks?

Thanks in advance.

Hi Paul,

Using the enhancement framework should be the way to go. This will allow you to add new attributes to a context node (or even new nodes) as well as many other entities to a Web Dynpro Component.

Best regards,

Thomas

Hi Thomas,

Are there other posibilities to extend extern context without using the enhancement framework?

Hi Paul,

In case an application provides self-defined exits, you could use dynamic programming inside and extend the context. Of course, it won't be as flexible as using the enhancement framework and design time checks cannot be used to detect problems.

Best regards,

Thomas
