Navision Attain was the name of the 3rd version of the windows based Navision released in 2001 as Navision Attain 3.01-. Version 3.00 had been released as Navision Solutions 3.00.
The recent merger with Damgaard Data, required the new NavisionDamgaard A/S to rethink their branding. The "name" Solutions was a perfect match in the setup where it was the base in a setup with different more advanced versions like Navision Manufacturing and Navision Advanced Distribution, where Navision was the only true platform. The result soon after the merger was Axapta became Navision Axapta and Navision Financials/Solutions became Navision Attain 3.01.
Besides the name change, then it included a large number of bug fixes over version 3.00. Unfortunately it introduced many more problems than it solved. There were a number of issues with Inventory Costing: Upgrading from 2.60M with lot or serial numbers or using average cost to 3.01 was an almost guaranteed disaster.
