Mirror accounting is used in several European accounting systems to ensure that inventory transactions are reflected immediately in the income statement, as well as in the balance sheet. This lets you analyze purchases and inventory movement in the GL in internal management reports.
You can apply mirror accounting to inventory control transactions only, such as PO Receipts, WO receipts, inventory movements, and SO shipments.
Mirror accounting links a set of source (balance sheet) accounts to a set of mirror (income statement) accounts. When an inventory transaction is posted that updates the source accounts, the system generates a mirror posting that updates the mirror accounts simultaneously.
