Together with the consulting firm BearingPoint, T-Systems won the federal state’s tender and has since confirmed its status as a reliable partner in multiple follow-on tenders – the Ministry reviews the rendered project services and issues a new call for tenders every four years.
“In recent years, we have handled a variety of larger and smaller SAP projects for the State of Brandenburg in this role,” explains Timo Czajka, Service Delivery Manager at T-Systems. They included the production of specifications, services for project implementation, the go-live, and the replacement of functional and upstream procedures with interfaces to SAP and system modifications. A deletion and archiving concept was also introduced this year as part of the project services.
One of the larger projects in recent years was the migration of the SAP system landscapes to a private cloud. Because it had become clear in the interim that dedicated infrastructures would not be viable for the future – especially since the changeover to SAP S/4HANA was already in the cards.
The federal state decided to carry out a two-step migration: in 2019, T-Systems migrated the extensive SAP landscape to a private cloud – smoothly and without interrupting operations. In this process, the database was transformed directly to SAP HANA. This met all the prerequisites for the extensive use of SAP S/4HANA.
But SAP S/4HANA doesn’t only involve a change of database structures, but also – and above all – standardization, and thus the process-based renewal of the SAP application layer. As part of the project order, BearingPoint and T-Systems have developed a migration strategy for the MdFE. The first step involves an analysis, to list the active functional procedures and explore their mapping in SAP S/4HANA. This will also entail changes to processes. In this context, the MdFE’s handling of custom code, i.e., special modifications to the workflows in the SAP systems, will also be discussed.
