The implementation of SAP S/4HANA is a process that requires many complex steps, all of which need to be accomplished properly to ensure a successful “Go-Live” when the company begins operating with the new system. The following SAP S/4HANA Migration Guide is an overview of the processes necessary to migrate enterprise-level databases and operational software to SAP S/4HANA. The process will be different for every company, but all will share some common procedures depending on the scenario involved.
SAP is an enterprise level software that encompasses every activity of a company. SAP has been in existence since 1972 when a group of IBM engineers set out to create a virtual management tool that would encompass all a company’s activities on a single platform.
This concept replaced previous solutions that had separate systems for each major company function, referred to as “legacy” systems. The limitation of these systems is that they are unaware of data points that need to be shared across all platforms. One example is the supply chain, which in older systems may have one module for ordering material, another for billing and another for inventory management. Consolidating these functions makes it possible to maintain proper inventory levels, manage expenditures, and reconcile payment to suppliers.
Migration is the term for moving data and software from one location to another. SAP is a system for processing data, and without proper installation of data, the system is like a bowling alley with no pins. This is why proper migration and installation of data is critical for an SAP S/4 HANA migration. This SAP S/4HANA Migration Guide is intended to provide a high-level overview of the process. There are three major classifications of data movement or “migration”, and every SAP project will fall into one of these categories.
Category 1) New Implementations
If a company has no centralized data management system, then all data will be moved from smaller local systems to the new SAP S/4HANA database. Current systems can be Oracle based, older IBM systems, or any number of local purchase order creation, HR, billing, accounting, and numerous other tools. In some cases, there may be an older ERP system in place, such as the IBM AS400.
No matter what, these are considered new installations because there is no SAP system currently in place.
This type of implementation is generally the most complex as data is stored in many locations and in many different formats. Unless the data is properly reformatted, it will not be possible to accomplish the migration. There are a number of tools available to reformat and prepare data for loading to SAP, but no matter what process is used, the data must be accurate and up to date. An SAP HANA implementation is only as good as the data that drives it.
Category 2) System Conversions
In this scenario, a company already uses SAP, but one of the earlier versions. These may be Oracle based or have another platform supporting the current version.
The advantages of SAPS4/HANA are faster data processing, a wider variety of reporting and Business Warehouse tools, and the option of running on the SAP-based cloud rather than in-house server structures. The migration is still critical, and the integrity of the data is just as important as with a new implementation. Again, there are many tools available to accomplish the cleansing of the data and the installation into the new system.
Category 3) Landscape Transformations
Many companies have multiple sites and multiple versions of SAP. This occurs when a company grows by adding new facilities, or through the acquisition of other companies who are already on an SAP platform.
A major advantage of the new SAP S4/HANA platform is the cloud-based infrastructure which can support many instances in multiple locations within one all-encompassing system.
Migration in this scenario has the added complexity of multiple sources of shared data, and it is, therefore, necessary to ensure that the data for each location is correct for the location.
The ultimate objective is a successful installation and Go-Live when the system is fully functional. There are numerous resources to assist any sized enterprise with their transition to SAP S/4HANA.
