Further development of the customer invoicing 2011
Project duration: 1 year
Brief description
Other requirements for the area of customer invoicing are implemented within the framework of maintaining the master data application. This concerns the improvement of plausibility tests during the creation of a customer invoice, the adjustment of the documents, and the calculation logic in accordance with legal requirements, especially for the Austrian energy market (utilization tax, green energy tax).
Supplement
The customer's master data application is based on a three-layer, service-oriented architecture (.Net-based thin client, application server, MS SQL 2008). The business processes are integrated in the master data application. Communication with the SAP system takes place via IDOCS and an in-house XML schema. The data are exported from the system in the direction of BizTalk and then forwarded to the SAP system. The messages from the SAP system are transferred via BizTalk back to the master data application and imported there. The internal processing happens on the basis of definite automatisms and manual processing by the user. Development is performed in C# based on the .Net 3.5 framework.
Subject description
The customer invoice is an essential component of the customer's business process, because, with the aid of monthly discount invoicing, payments for the energy delivery and other services are collected here. The end of year settlement is created at the end of the business year. Further development in this area is functionally defined primarily on the basis of statutory requirements. These affect the calculation of the individual components of the invoice and the layout of the document. In Austria, for instance, the electricity mix must be graphically formatted and presented in a clearly comprehensible manner. Moreover, adjustments based on the customer's own new price models are also required.
