Execute mode
You can do Fnc-REST calls using execute and interact modes. Execute is appropriate for machine integrations and corresponds to <resource path="service/execute"> in the application.WADL.
Execute mode is a one-shot call with one request and one response. You can separately ask for metadata (metadataMode="MetadataExcluded") using this function.
You can display any MDP program information, errors and notifications using execute mode.
