Short description:

Within the framework of legal requirements in energy trading and on the basis of new requirements, the incoming document entry system will be further developed in 2021 to make it fit for the future. The focus will be on the implementation of a decision tree for electronic delivery bills and the expansion of invoice verification to include the principles of market communication.


In the further development to ensure the future viability of the incoming document entry system, current, productive, technical and functional challenges must be overcome. This is done in consultation with the specialist department via database (SQL) or code changes (.Net C#) to the application. As a result of legislative changes in energy trading or as a result of changes to the adjacent internal systems with which this application communicates, adjustments must be made on an ongoing basis.

Technical description:

The existing incoming document entry system is an application for entering and validating incoming supplier documents (invoices, budget billing amounts, reminders). Booking data is forwarded to SAP via an interface and consumption data is transferred to a controlling system. In 2021, the adjustments will be made in line with the requirements of the German Association of Energy and Water Industries (BDEW). (BDEW) insofar as the processing of electronic delivery bills (MSCONS) for quantity verification between data of the metering point operator and the network operator will be implemented on the basis of a predefined decision tree. Furthermore, the invoice verification (INVOIC) against these delivery bills is simplified. The use of energy data from an adjacent system is made more granular than before.
