Preparing the Web Dynpro Component

Context

Whether you have to change your Web Dynpro component to enable it to be used as a CHIP depends on how it is to be used. If you only want to display the Web Dynpro component and use its functions, you only have to create one CHIP for the component. If you want your component to have ports for communicating with other CHIPs, further steps are necessary.

Components of the Dictionary structure that are based on the port type can be used as inport and outport parameters provided the component type is an elementary data type. Table types of simple Dictionary structures can also be used.

Nested structures, table types, and reference types are not permitted. Dictionary structure components of this type therefore cannot be selected as port parameters.

Procedure

To create an outport in your CHIP, you have to fire an event in your Web Dynpro component.

For more information, see Defining an Event for an Outport.
To create an inport in your CHIP, you have to implement a method in your Web Dynpro component with which you can process, for instance, the data that has been transferred through wiring from another CHIP.
