After you register an Integrator Message Flow Component (MFC), from the Copilot main window, select Dataset > Commit changes.
This enables Composer to import a reference to the registered MFC from the Integrator Server instance.
After you commit the MFC registration on the Integrator Server, in Composer, use the Import Object-Set command to import the Integrator Server object set. This object set includes a reference to the registered MFC. After executing the command, the MFC is available for selection in the Integration-Task configuration.
