Create a development component in which you want to import an RFC function module.
You have found an RFC which you want to import into the workspace.
More information: Searching for RFC Function Modules
When you discover the remote function call (RFC) function modules which you want to consume, you can import these RFCs in the corresponding development components (depending on the perspective and framework).
The system imports the RFC function module into the development component which you chose. The service adaptation tools convert the RFC module to a WSDL document which you can use as a source to create a consumer for the RFC.
