Is B1if the new B1iSN?
According to Heinz Pauly, the father of B1 Integration, both products are still supported, but unofficial rumors and comments leads to believe that eventially B1if will replace B1iSN.
Both products are relying on the same platform - Business One Integration Platform, or for short B1iP.
B1iSN was originally created to provide a bridge between the two product families of SAP - R/3 and Business One. This tool enabled the integration of central Headquarters running R/3 with smaller subsidiaries running SAP Business One. Hence the name B1iSN - Business One Integration for SAP Netweaver.
As the product evolved, it baceme the central integration tool for Business One, just like XI is for R/3. The tool was rewritten from the ground up, emphasizing ease of use and provides smoother integration into Business One data. The initial name was Business One Integration Center (B1iC) and later renamed to Business One Integration Framework (B1if). This new tool ships and installs together with the SAP Business One product itself free of charge. This allows SAP to ship external Add-Ons Like mobile integration and Xcelsius dashboard together with at business management application.
