Fixed Assets
The Fixed Assets functionality interacts with the Financial Management functionality.
The Acquisition Costs and Depreciation of the company's fixed assets have probably already been posted to the General Ledger by posting manual transactions using the General Journal. But this will have to change in the future. Those transactions will not be posted anymore by creating manual transactions, but using standard functionality offered by the Microsoft Dynamics NAV Fixed Assets module. The accounting procedure will have to be changed.
Fixed Assets also interact with Microsoft Dynamics Sales and Purchases functionalities, as fixed assets can either be sold or purchased using those functionalities. The user's procedures to post those transactions will change when the new functionality starts being used.
