Navision Solution is the name for Navision which until now had the shortest life span. The major difference between version 3.00 and 3.01 was the name change to Navision Attain 3.01.
When Navision Financials version 2.0 had been released, it was followed by some new versions of Navision having special functionality, not contained in the standard Navision. This was Navision Advanced Distribution and Navision Manufacturing.
So "Solutions" would had been a common brand for the different versions. But the release was also shortly after the Navision/Damgaard merger. And as soon as Navision Software and Damgaard Data had their new combined branding in place, they replaced the name Navision Solutions with Navision Attain 3.01. Navision Solutions was only released in group 1 countries.
