The first product name for the SAAS offering of Dynamics NAV 2017, that used to be known as Dynamics 365 "Project Madeira", when it was released in October 2016.
Dynamics 365 for Financials, Business Edition was its full name. Business Edition as opposed to the Enterprise Edition, where Dynamics AX now were called Dynamics 365 for Operations, Enterprise Edition.
The names led to great confusing in the channel and among potential customers. Enterprise customers couldn't understand that there were no "Financials" application for them.
The name was changed again in 2017 to Dynamics 365 for Finance and Operations, Business Edition, just as AX got the same name, just Enterprise Edition.
