Business-to-Government Integration Reference Architecture

Overview​

In many countries or regions, organizations must comply with local requirements mandating the submission of electronic documents such as invoices, summaries, transport registrations, and statutory reports to external communication parties. Depending on the exchange model, these documents are transmitted through an authority, a regulated service provider, a regulated network, or directly to the business partner. The actual exchange of data may be fully electronic or require manual download or upload.

This reference architecture follows the SAP Integration Solution Advisory Methodology, defining B2G integration as an integration use case pattern under the process integration style. It covers integration domains such as Cloud2Cloud and Cloud2OnPremise.
