Further development of an incoming document entry system

Project duration: 1 year, 1 month

Brief description

The incoming document entry system will be further developed in 2021 within the framework of legal requirements in energy trading and on the basis of new requirements. The focus will be on adapting the electronic processing of delivery bills and expanding invoice verification to include market communication basics.


In the further development to ensure the future viability of the incoming document entry system, current, productive, technical and specialist problems 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 changes in legislation in energy trading or in the adjacent internal systems with which this application communicates, adjustments must be made on an ongoing basis.

Subject description

The existing incoming document entry system is an application for entering and validating incoming supplier documents (invoices, reminders, budget billing amounts). Booking data is forwarded to SAP via an interface and consumption data is transferred to a controlling system. In 2021, the changes will be implemented due to the requirements of the German Association of Energy and Water Industries (BDEW). (BDEW) for market communication in the system will be further developed. The processing of electronic delivery bills (MSCONS) will be changed to processing based on a decision tree specified by BDEW. The delivery bills are used for quantity verification between data of the metering point operator (own data and third-party data) and the network operator against the invoice (INVOIC) of the distribution network operator. In addition, a display and use of energy data from an adjacent system are further developed.
