Before you can run a service interface that has been generated using the Interface Mapping Toolkit, it needs to be deployed to an enterprise server. The service interface comprises the mapping information and might include the COBOL program and any required data.
During development the developer usually deploys the interface automatically using the Deploy tool in the Interface Mapping Toolkit. Once it is ready for use in a production environment however, you should deploy it using the .car file that was produced when the Deploy tool was run for the last time.
