Short description:

An energy trading company is expanding its customer base for the provision of alarm services to include other EU countries. Previously, the services were only provided within Germany. With the acquisition of foreign customers, the billing and booking processes as well as the documents must also be adapted according to tax law requirements. In addition, existing master data must be transferred to the German client and consistent maintenance must be ensured. Additional master data must be maintained and transferred to the ERP system.


The master data system is an internal .NET solution with MS SQL Server connection and a BizTalk communication interface to the SAP systems, in which any booking processes take place. The data for the alarm services incurred is imported from an existing external SQL database. The existing contract and billing structures, as they already exist for energy supply contracts, will be used and adapted to the new requirements. The focus of the adjustments is on automating the contract and billing processes.

Technical description:

As part of the expansion of the customer base to include other EU countries, the automatic processes for the administration and billing of alarm services must be adapted. The focus here is on the correct VAT presentation of the postings in the own as well as in the recipient company code. The documents must be expanded to include passages for the payment of sales tax and the specification of the sales tax identification number. This also affects the maintenance and transfer of master data.
