End of Support for SAP IS-U for Utilities

SAP IS-U is an ERP (Enterprise Resource Planning) system developed specifically for the energy supply industry. SAP IS-U enables companies to optimize their business processes and thus save costs. SAP IS-U offers a wide range of functions that are tailored to the needs of the energy supply industry.

SAP IS-U offers a wide range of functions, such as billing for electricity, gas, water and heating requirements, and managing customer data. SAP IS-U also enables companies to automate their processes and thus save time and costs.

IS-U is primarily used to provide information on inventories as well as costs and revenues. IS-U enables companies to reliably monitor their inventories and thus ensure effective operational control. In addition, IS-U enables companies to increase productivity and minimize costs.
