Ingolstädter Kommunalbetriebe AöR is responsible for wastewater disposal in Ingolstadt and has been using BaSYS for this work for several years. In order to be able to manage the data stock with other authorities and offices in a uniform manner, a connection to SAP was created. With the communication interface “SAP 2 BaSYS”, information is communicated bidirectionally between BaSYS and SAP. SAP applications can specifically access the diverse and detailed factual data of the objects managed in BaSYS. On the other hand, for example, SAP object selections can be controlled with the graphical BaSYS plan output.
