+**Multiple Companies**
+If only one Company was registered in [Proxy Setup with /UBC/S17_SETUP_PROXY](#proxy-setup-with-ubcs17_setup_proxy), the addon chooses the one and only company automatically.
+If more than one company was registered, obviously any point has to define the correct company. We recommend to link a SAP company code to the Proxy during [setup tasklist](#proxy-setup-with-ubcs17_setup_proxy). SAP Company code is only an informative field, but a flexible way to link SAP companies to S1SEVEN company ids without any logic or configuration changes after all.

+> If multiple Companies were registered, it is **mandatory** to add some logic to choose the proxy.

+In the new BO class you will create below, redefine method `choose_proxy_by_input`. It is meant to choose from a list of proxies based on given input data. Cast the generic input data to the concrete type you chose in your implementation method `create_type_input`. See `/UBC/CL_S17_BO_CERT_OUT_IDOCEX` for an example implementation to copy from (its based on SAP Company code linkage, but you are free to determine that differently, e.g. Customizing/BRF+).
