The term B1i is addressing a bundle of solutions to integrate Business Applications of SAP.
All B1i solutions are based on a common SAP technology layer (B1iP). This layer is a break through innovation in integration to answer the typical nightmare of complexity and diversity with a strict model-driven approach. Instead of complex, high-cost implementation, it enables strong low-cost, reliable integration solutions with minimal requirements to resources and skills.
To run high integrated apps with state-of-the-art integration software is affordable only for large enterprises with a huge IT budget. With B1i, SAP opens now the high integrated world even for Small Businesses.
The SAP Business One Integration framework (B1if) is integral part of the SAP SB ERP system SAP Business One 8.8.1. It is used by SAP to enable inbuilt functionality like Dashboards, the B1 Mobile solution or the Datev-HR integration and optionally allows the customer to implement the individual integration to his business partners in a high efficient way by the graphical flow designer. B1if is high declarative with strong focus on reliability. It provides all needed connectivity be it the old fashioned like file, ftp, sql, the new web 2.0 technologies or native support for SAP R/3, SAP Business One, SAP XI, etc.
The Business One Branch Consolidation (B1BC) is running on top of B1if. It is an out-of-the-box solution for customers which are running multiple SAP Business One systems connected to each other. B1BC is automatically synchronizing the business data and provides a strong financial consolidation.
SAP Business One integration for SAP NetWeaver (B1iSN) is a special solution for customers, running SAP NW components in their headquarters and SAP Business One in their subsidiaries. B1iSN is running centrally in the HQ and integrates the subsidiaries into the overall enterprise business processes. You can run B1iSN integrated via SAP XI or with direct connections. B1iSN comes along with out-of-the-box integration scenarios, e.g. for master data, sales processes and reporting and allows the implementation of any individual scenario to the customer’s needs.
This blog is addressing all kind of information around the B1i solutions, from business news to deep technical development questions.

Great idea to address this theme with a special blog ! I’m curious on the discussion and news.
Thank you very much !
