Each window incorporates an inbound and an outbound plug and they can be included in a navigation chain. Inbound plugs within a window lead from the outbound plug of a view to the embedding window. Similar to all other inbound plugs, they constitute an occasion and thus call the event handler assigned to them.
Controllers are used to describe how a Dynpro application replies to user interactions. Each view has one controller which is responsible to perform actions as per the user’s interaction.
