Incoming document entry system: Reverse charge procedure

The existing incoming document entry system is an application for entering and validating supplier incoming documents (invoices, dunnings, discounts). Since 01.09.2013 in the electricity sector and 01.08.2013 in the gas sector, the reverse-charge procedure is possible and legally required for supplier invoices for energy deliveries or that include energy components. To enable this, the master data system must contain certificates approving the resale of energy. In the incoming document entry system, the certificates are checked when invoices are entered without VAT. If the reverse-charge procedure is not yet used, there is an option to configure these exceptions on a period-specific basis to give the billing party the option to update their system. Posting data for the reverse-charge documents are transferred to the SAP system with a special VAT ID.
