You can calculate the inventory based on the First In First Out (FIFO) valuation. This process looks at the current stock of each inventory item and then goes backward through the receiving records until it reaches the level of the current stock for each item. It then calculates the cost of the inventory based on a weighted-average cost of received merchandise.
Run this process only once. If you run the process twice, you cannot restore the original cost valuation.
