Asynchronous request processor

The asynchronous request processor transaction completes any API request or service request in the offline mode. It picks up the API messages or service messages from the YFS_ASYNC_REQ table and invokes the corresponding API or service. The messages can be inserted to the YFS_ASYNC_REQ table by using the createAsyncRequest API.
