Trade accounts receivable invoices not invoiced yet represent goods and services that have been delivered but not yet invoiced.
The increase in trade accounts receivable invoices not invoiced yet is connected in particular with a year-on-year increase in volumes and prices of energy products, which likewise had an impact on trade accounts payable to be received under deferred income and accrued expenses (see Note 33).
