Hello Fernando,
The support for SAGA credit through the Configurator was actually replaced some time ago with the usage of SAP's Centralized EFT solution (aka - Transnet). Centralized EFT is a centrally managed switch where you can write custom APM's (Application Programming Modules) to interface with different service providers like SAGA.
It is possible that a SAGA APM already exists, but I am not certain.
Hope this helps.
Steve
