The Solution – KTern’s Digital Maps

All the above questions may seem too intimidating to answer in the first place and especially without any data and insights. Typically, these questions are answered by conducting workshops for 3 to 4 months, paying some top dollars and making sense of the data.

But, what if we told you that, there is a product which has been developed using 15 years of SAP Tribal knowledge and can help answer all the above questions with data from your own SAP Landscape?

KTern’s Digital Maps connects to your existing ECC system and reads the data. Using the rule engine called S/4HANAPEDIA, KTern provides analytical insights in terms of how the data is structured and organized within your system. It enables you to understand the implications of the transition from an existing SAP ERP system to SAP S/4HANA. You can also identify the necessary preparations and pre-projects in the current system landscape, long before an SAP S/4HANA system conversion project starts.
