This is applicable for both type of RFCs, between ABAP systems and external calls to ABAP systems Type I - entries specify ABAP systems connected to the same database as the current system. Create evaluation Callback This callback will compute the exact match score using the validation data after every epoch. The IAsyncStreamReader type works much like an IEnumerator. We use the keyword stream to indicate that the server will send a stream of messages. For example, specify ["message", "edited_channel_post", "callback_query"] to only receive updates of these types. For example, if we’re given a REST endpoint that returns some data, such as GET /users, we can simply open it in a browser and we’ll see the result.
