The SAP CC Online agent is a real-time agent that can be used to send charging request to SAP Convergent Charging and to handle the answer.
The SAP CC Online agent communicates with the workflow by using a dedicated set of UDRs. The The SAP CC Online agent accepts any charging request UDR as input. A CCCycleUDR, containing both the request and the answer will be returned as output. For further information about the SAP CC UDR types, see see SAP CC UDRs(3.1).
Asynchronous Communication
To provide a fast and efficient charging capability, the SAP CC Online agent relies on the Asynchronous Charging Client (AsynchStatefulServiceClient). For further information about the SAP CC AsynchStatefulServiceClient API, see the SAP AsynchStatefulServiceClient documentation.

The SAP CC APIs that the SAP CC Online agent depend on do not support setting the itemImmediatelyLoaded flag for ChargingOutputContext. As a result, the SAP CC Online agent cannot support scenarios such as CIT creation via charging requests. |
In order to reduce the number of connected clients on a SAP Convergent Charging core server, a pool of shared clients exists on the side. It means that all the workflows running in the same EC will not instantiate their own connection with SAP Convergent Charging, but instead use one shared client.
Based on its configuration (Host, Port, Timeout and Flow Control), the SAP CC Online agent will pick a mapping client up from the pool when the workflow is initialized. If there is no client matching a particular configuration, a new client will be added to the pool. For further information about how to configure the client, see SAP CC Online Agent Configuration(3.1).
