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 response from the server.

The SAP CC Online agent communicates with the workflow by using a dedicated set of UDRs. 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 9.6869.4 SAP CC UDRs.

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.

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 or ECSA 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 9.6869.1.2 SAP CC Online Agent Configuration.
