The check cost prices report in the inventory closing procedure should consider the site of the transactions when retrieving the cost price (you can have different active cost prices for an item/variant per site). Item cost price: system finds the latest active item cost price using the site of the smallest cost price receipt transaction for the item (of item-variant if cost by variant is active). The las active item price should be considered only for the site of the receipt transaction. Median: system calculates the median of the receipt transactions for the item (or item-variant if cost by variant is active) independent of the site. The site should be considered.
