How to Migrate Data from SAP ECC to SAP S/4HANA

The transition from SAP ERP Central Component (SAP ECC) to SAP S/4HANA (the next-generation ERP suite) is a critical step for organizations seeking to leverage the latest technological advancements and gain competitive advantages. One of the most crucial aspects of this transition is migrating data seamlessly to ensure the smooth and successful adoption of SAP S/4HANA.

In this article, we’ll provide you with a step-by-step plan to guide you through the data migration process.

What is SAP ECC?

SAP ECC is an ERP system that streamlines company operations through integrated applications, ensuring consistent data storage, retrieval, analysis, and processing. It facilitates synchronous data exchange across departments, allowing real-time recording and processing of business processes from order to delivery. Notable features include high portability and compatibility with standard operating systems, mobile devices, and various databases, enabling seamless integration with external business applications.

The 2030 end-of-extended-support period for SAP ECC is approaching quickly. SAP offers considerable performance improvement with SAP S/4HANA to replace the previous ERP generation. 

How SAP S/4HANA Makes a Difference for Business

SAP S/4HANA provides a foundation for the future, ensuring companies stay at the forefront of technological advancements. As SAP ECC reaches its end of mainstream maintenance by 2030, migrating to SAP S/4HANA becomes essential to continue receiving support and updates from SAP.

By embracing the latest platform, companies can leverage continuous innovation, stay compliant with evolving industry standards, and safeguard their IT investments for the long term. Let’s look at the benefits that SAP S/4HANA offers businesses.

SAP S/4HANA database technology

SAP S/4HANA is a business suite developed to run exclusively on the HANA database. Thanks to its in-memory technology, the HANA database stores data in the main memory instead of on the hard disk, significantly speeding up data analysis and processing. In addition, HANA works more efficiently than conventional relational databases because it can access data tables that are row-based as well as column-based. This leads to faster reading and is particularly suitable for analyzing large amounts of data.

Cloud-based ERP

Another difference from the ERP predecessors is that SAP S/4HANA is not only offered as an on-premise system but also as an in-cloud solution. Therefore, the server infrastructure required for data processing is no longer located locally in the company but is provided externally by SAP itself. This saves effort and costs in administration and maintenance, ensuring that the company always uses the functionality of the current software version.

Greater flexibility

One of the key benefits of SAP S/4HANA over SAP ECC is that SAP's latest business suite gives you multiple deployment options. Host SAP S/4HANA on-premises or choose a public, private, or hybrid cloud solution. Global access to your company data makes your company more flexible and agile.

The migration from SAP ECC to SAP S/4HANA allows companies to unlock real-time insights, streamline processes, drive innovation, and future-proof their operations. It is a strategic move that propels businesses toward digital transformation, enabling them to thrive in a rapidly changing business landscape.

Now, let’s discuss the scope of actions for successful data migration.

Assessing the Data Landscape

Thorough preparation for the data migration process is imperative for companies as it ensures a seamless and successful transition to a new system. Analyzing all available data will identify potential challenges or inconsistencies and help implement robust data cleansing, mapping, and transformation strategies. You can use the following recommendations for conducting preliminary activities.

  1. Understand the current data landscape in your SAP ECC system. 

    Understanding the current data landscape in your SAP ECC system is crucial before embarking on a migration project. This involves comprehensively analyzing the system's data volume, quality, and relevance.

    By delving into the intricacies of your data, you can gain valuable insights into its characteristics, such as the size of the database, the number of tables, and the types of data stored. This understanding will help you assess the scope of the migration, plan resource allocation, and estimate the time required for the process.

    Action points:

    • Conduct a data volume analysis.
    • Assess data quality and relevance.
  2. Analyze the data volume, quality, and relevance for migration

    Analyzing the data volume, quality, and relevance is vital in the data migration journey. It entails examining the volume of data stored in the system, including tables, fields, and records. This analysis will help you clearly understand the data scale and complexity, enabling you to determine the resources needed for effective migration.

    Additionally, assessing the data quality will help identify any inconsistencies, errors, or duplicate information that may exist. Evaluating the relevance of the data will help prioritize the migration effort by focusing on the most critical and essential data for the new system.

    Action points:

    • Cleanse and remove any unnecessary or outdated data.
    • Perform data validation and ensure data accuracy.
  3. Identify any customizations or modifications that may affect data migration

    During the analysis phase, it is crucial to identify any customizations or modifications that have been made to the SAP ECC system. Customizations refer to any changes or enhancements made to the system's standard functionality, such as adding fields, modifying existing tables, or creating new ones.

    These customizations can significantly impact the data migration process as they may require special considerations and additional resources to ensure a smooth transition. Understanding and documenting these customizations will help mitigate potential challenges during the migration, ensuring that the data is accurately transferred and integrated into the new system.

    Action points:

    • Familiarize yourself with the new data structures and concepts in SAP S/4HANA.
    • Understand the changes in data models and table structures.
    • Identify any new data fields or structures that may impact migration.

The Types of Data During Migration

During data migration from SAP ECC to SAP S/4HANA, the following types of data are typically transferred:

Master data

Customer, vendor, material, and other master data relevant to business operations

Transactional data
Sales orders, purchase orders, invoices, payments, and other transactional records
Configuration data System configurations, settings, and parameters customized for specific business requirements
Organizational data Organizational structures, hierarchies, and relationships within the company
Open Items Open invoices, outstanding payments, and pending transactions
Historical data Historical records and data used for reporting, analysis, and compliance purposes
Authorizations and user data User roles, authorizations, and access rights for the new system
Workflow and approval data Workflows, approval processes, and associated data for business processes

Please note that the specific data to be migrated may vary depending on your organization's requirements and the scope of the migration project.
