Data Update When Posting an Invoice 

When you post an invoice, the system carries out the account movements and updates the following (See also Account Movements When Posting Invoices):

• The system generates a Financial Accounting document that displays the accounts involved in the posting and the amounts posted to these accounts.
• The system creates a purchase order statistic for each item in the purchase order. Each posted invoice is included in this file. In this way, it is possible to display a current overview of the purchase order history at any time.
• The moving average price is updated in the material master record if the price of the invoice deviates from the purchase order price (See also Price Variance: Account Movements).
• If the invoiced price differs from the price in the purchase order for a material with moving average price control, the value of the stock is updated in the material master record. (See also Price Variance: Account Movements).
