If an item uses Standard Cost as Costing Methodand the purchase price of the Item on a Purchase Order is different than the Item’s Standard Cost, the Item Receipt posts the difference to the Purchase Price Variance (PPV) account specified on the item record.
If the GL impact of the item receipt posts the entire amount to Accrued Purchases Account (Inventory Received Not Billed) account and not to the Purchase Price Variance account, it may be because it may be because the schedule Inventory Costing field in Inventory Costing Preferences is set to Based on custom schedule or Every Hour in customer’s account.
If customer’s schedule Inventory Costing is set to these options, the system just uses the rate on the Item Receipt for the Asset Account value, and sets a 0.00 to the Purchase Price Variance (PPV) account upon saving the transaction. Then, costing will run asynchronously depending on the customer’s inventory costing preferences to set the real Standard Cost and Purchase Price Variance.
