Hi Pradeep,

The faceless WDA component  is a component without any views,windows. It has only component controller and custom controller if any.

Use of faceless component:

Let us say we have a very complex requirement where in lot of components need to developed and integrated to work each other.

If there is a need to common data and attributes need to mapped and used in many components,

•      We separate the common data into a faceless component which just holds the common data / key data which can be used further e.g.: zwd_input_parameters
• Now, we use this component inside other components ZWDA_SALES,  ZWDA_PURCHASE and map the context using external mapping

If we want to re-use component with views & windows again and again in other components, it will be heavy component as it has graphical elements like views , windows in it.

So,faceless components com into picture without views/windows.

Hope this helps you
