By converting its existing SAP R/3 system PJA to SAP S/4HANA, Jenoptik aimed to harmonize processes, master data and reporting. The goal of the project was to provide optimal support for the global business and facilitate future leaps in innovation.
The R/3 system, which had grown over the years and contained 30 plants, 40 company codes, and around 20 sales and 10 purchasing organizations, needed to be completely migrated and then archived. Among other things, this involved a plant split and merge within a company code across all applications and including the full history.
To implement the organizational changes and planned innovations as quickly as possible, the first step was to securely switch to an SAP S/4 system with the most important functions. This is to be followed by an innovation phase in which further useful S/4 functions will be introduced.
SNP worked with NorthWestern Energy and other partners to design, plan, and execute a successful migration strategy. The core project involved upgrading SAP ERP to SAP S/4HANA. The move to S/4HANA provides NorthWestern Energy with a faster, higher- performing ERP system that reduces “technical debt”, eases user adoption through the new Fiori UI, and allows the implementation of future SAP innovations and support.The entire legacy ERP portfolio was transformed by this upgrade.
Traditionally it takes companies about two years to upgrade their SAP ECC system. Using IBM’s Rapid Move powered by SNP’s one-step BLUEFIELDTM approach, NorthWestern Energy was able to complete the S/4 migration in just nine months.
