ARCHITECTURE OF SAP NOTA FISCAL ELETRÔNICA

SAP Nota Fiscal Eletrônica (SAP NFE; SAP Eletronic Invoicing for Brazil) utilizes different components to meet government requirements, all while enabling a high degree of flexibility to ensure your business benefits. The following graphic shows all the components included in the NFE application-shipment that you need in addition to the business processes in SAP ERP.

• NFE core application
  The NFE core application contains the administration and monitor workplaces for the outbound scenario, and the fiscal and logistic workplace for the inbound scenario.
• SAP NetWeaver Process Integration (SAP NetWeaver PI)
  If you already use SAP NetWeaver PI to communicate between different systems, you can easily implement the additional content required to communicate with the authorities without changing your existing setup. SAP NetWeaver PI offers you all the technological and messaging capabilities you need to send NF-es and all other NF-e related messages in a compliant manner (including HTTPS and SOAP).

Integration

Inbound and Outbound Integration

Based on your existing system landscape, you can connect one or several logistics systems as back-end systems to send and receive NF-es for SAP NFE, and to use SAP NFE as the central communication platform for your NF-e processes. The back-end systems can be either SAP ERP or any legacy system that provides the billing data and tax-related information that the authorities require. The interface implementation necessary to connect SAP ERP to NFE is part of the standard delivery.
