Fiscal Inventory Valuation
You must submit an annual report that shows the monetary value of inventory items for the fiscal year. According to the Italian requirements for fiscal inventory valuation, you must calculate the following cost types:
Year average cost
Weighted average cost
First in, First Out (FIFO) cost
Last in, First Out (LIFO) cost
Discrete LIFO cost
Fiscal Inventory Valuation in Microsoft Dynamics NAV
Initially, you must set up the fiscal inventory valuation for all cost types in the Item Costing Setup window and the Item Card window. For more information, see How to: Set Up Fiscal Inventory Valuation.
When you set up Microsoft Dynamics NAV for the first time, you must enter the inventory item ledger entries for the first year in order to calculate the item’s valuation. You can do this in the Before Start Item Cost window. For more information, see How to: Set Up Initial Item Costs.
To calculate discrete LIFO cost, you must set up information in the Item Card window and the Subcontracting Prices window.
The discrete LIFO cost can only be calculated for items for which the Inventory Valuation is set to Discrete LIFO in the Item Card window.
After you set up the discrete LIFO cost calculation, you can post sales and purchase transactions based on year-end costs.
End of Year
At the end of the fiscal year, you can run the Calculate End Year Costs batch job to calculate the fiscal inventory value of each inventory item according to the required valuation methods. The results are shown in the Item Cost History List window. Then, you can run the Fiscal Inventory Valuation report and the LIFO Valuation report to show the inventory valuation.
For year-end operations, such as calculating the profit and loss during a fiscal year, there is a definitive period and a non-definitive period. If the Competence Year field in the Item Cost History List window is equal to the fiscal year end date, it is a definitive period, and you cannot recalculate data for a definitive period. If the definitive data differs from the fiscal year end date, then it is a non-definitive period. There should be data for at least one non-definitive period to perform calculations or partial calculations.
