Navigating SAP S/4HANA Migration with Confidence

Due to the increasing pace of change within the digital economy, there has been much pressure on organizations across Nigeria, specifically in Abuja, to upgrade their enterprise systems in order to remain competitive. One of the most impactful technology changes that businesses are undertaking today is in digital transformation via migration to SAP S/4HANA. For many organizations, this typically includes a substantial change from legacy enterprise platforms to new, advanced, intelligent ERP systems. While migrating enterprise data can pose many challenges, they can be overcome through careful planning, well-structured strategy development, and sufficient technical expertise.

This article discusses some of the frequently encountered enterprise data migration challenges faced by organizations in Abuja, Nigeria, and provides outlines of best practices to facilitate a successful transition, particularly for those transitioning to SAP S/4HANA from SAP ECC.

Understanding the Stakes: Why Data Migration Matters

Migrating data does not simply consist of moving the information from one source to another; it incorporates changing the information, assuring it is accurate, and fitting it into contemporary platforms (e.g., SAP S/4HANA). The banking, manufacturing, oil & gas, and public sector industries of Abuja have some of the highest stakes when it comes to data migration as they all rely on having an adequate volume of clean and accurate data to operate effectively, comply with regulatory requirements, and make decisions in real time.

When moving from a Legacy System Upgrade initiative to full Enterprise Resource Planning (ERP) modernization, many opportunities for efficiency, automating processes, and accessing analytics exist; however, unless an adequate data migration framework is established, they will be unable to realize those benefits.

Key Data Migration Challenges in Abuja, Nigeria

1. Quality And Standardization Of Data

Among the many challenges faced by organizations today, the biggest is having inconsistent or poor-quality data. When migrating to SAP S/4HANA, there can be multiple or inaccurate records of entities in legacy systems, some of which are old, incomplete, or inaccurate. These record discrepancies may result in errors post-migration and, as a result, interruptions to business processes and reporting accuracy after migration.

For example, if two customer records representing the same entity existed in the original system, where one was created manually while the other was created through an automated process, this could create issues when these records were integrated into the new ERP system.

2. Lack Of Planning And Strategy

One reason why many migrations fail is the absence of an SAP S/4HANA Migration Strategy. Abuja organizations frequently overlook the complexity related to migrating larger data sets along with new organizational business processes.

They may also fail to adequately discover or profile their data increasing to the scope of the migration, delays to the timeline, and unexpected additional costs.

3. SAP Tools Technical Complexity

While tools such as SAP S/4HANA Migration Cockpit can provide strong frameworks for Extraction, Transformation, and Loading (ETL), they all require specialized skills and governance. Many local teams are not familiar with these tools; therefore, their use tends to lead to user error through misconfiguration, resulting in bottlenecks during migrations or halting the migration process altogether.

4. Legacy Methodologies That Lack Communication

Many companies manage a variety of different legacy, non-integrated software Applications.... These could include finance, HR, purchasing, and specific, custom Applications. When a company upgrades from SAP ECC or other legacy Application(s), it can be a major challenge to get the various data structures in alignment before the cutover; this challenge is especially difficult when you can't find documentation or the documentation is old and/or out-of-date.

5. Lack of Skills and Change Management

Data migration requires many different teams working together across multiple functions. While the IT team is usually overloaded, the business team(s) generally do not have a good understanding of how the technology works before the cutover, so consequently do not receive any training on how to use the new system. This situation can lead to user resistance to the new system and undermine the long-term success of the solution.

Best Practices for Successful Data Migration

Migrating to SAP S/4HANA need not be tumultuous. Abuja organisations with the right strategy can leverage data migration to gain a competitive edge.

1. Assess & Cleanse Data Early

Before commencing the migration, carry out a comprehensive assessment of the data. Data profiling can help identify duplicate records, null values, and inconsistencies within the format of the data. You should utilise data cleansing tools and establish data quality metrics before the migration to guarantee that the data being loaded into your new system is complete and accurate. This first step lays the foundation for a more efficient legacy system upgrade.

2. Create a Full-Fledged SAP S/4HANA Migration Strategy

Adopting an effective SAP S/4HANA migration strategy is extremely important. The SAP S/4HANA Migration strategy should stand on the following four pillars:

• A comprehensive inventory of data sources

• Defined phases of data migration

• An identified mapping structure from Legacy data models to the new schema/model

• KPIs will be established to validate the success of the data migration

By developing effective technical processes in-line with the business objectives, you will help to mitigate any risk and ensure alignment of all stakeholders throughout the project.

3. Utilize the SAP S/4HANA Transition Cockpit

The SAP S/4HANA transition cockpit is an SAP product designed to facilitate the transition from a legacy system to the S/4HANA environment. The S/4HANA transition cockpit provides automation for most of the extraction and transformation of data, supports bulk loading, and generates log files for monitoring and troubleshooting.

Experienced consultants will create workflows in the S/4HANA transition cockpit for you that will be tailored to your specific data structure and business processes, enabling their execution to occur more smoothly.

4. Focus on Data Governance and Documentation

Ensuring strong data governance ensures that your data is accurate, secure, and compliant during the entire migration project. Create governance policies defining the following things:

Who is responsible for each piece of data

How will you approve changes to your data

How will you validate the integrity of your data

Documenting each step of the project will allow you to create an audit trail as well as a roadmap for future improvements to your data's quality.

5. Investing in Workforce and Change Management

Having a technical strategy only isn't enough - organizations will need to prepare their workforce for changes as well. This means regular training on the SAP S/4HANA system, as well as providing avenues for employees to give feedback to assist in the transition and create change agents within departments to support their peers during the transition.

Strong change management plans help reduce resistance, increase user adoption, and enhance the value of your investment quickly.

6. Testing, Correcting & Retesting

Never assume that the migration will work perfectly on the first attempt; there should always be multiple rounds of testing, including unit testing, integration testing, and user acceptance testing (UAT), prior to going live. Validating data accuracy and business process flows is key to a successful go-live. Performing early testing will help avoid expensive roll-backs and operational downtime due to an unsuccessful go-live.

Conclusion

The data migration process is critical to your organization's success in implementing digital transformation, and is especially true for organizations within the capital of Nigeria, where organizations are moving to utilize more advanced ERP systems such as SAP S/4HANA. Understanding the typical migration challenges and following recognized best practices will allow businesses to successfully navigate this challenging transition with increased confidence.

Whether upgrading from SAP ECC, modernizing legacy applications, or doing a complete digital overhaul, having a good strategy and being disciplined with operational execution will make a huge difference in the outcome of your migration.
