SAP S/4HANA Finance Migration: Steps and Challenges

Discover key steps, benefits, and challenges of SAP ECC to SAP S/4HANA Finance migration to improve financial accuracy, reporting, and business efficiency.

Companies need reliable financial data in order to control their finances, manage cash flows and make business decisions. However, legacy enterprise software can make the process of financial reporting and analysis more difficult with the development of the company.

Successful migration from SAP ECC to SAP S/4HANA Finance migration includes not only transfer of financial data to a new environment but also several other steps.

Why Do Organisations Transition from SAP ECC to SAP S/4HANA Finance?

Classic SAP ECC systems have been providing services for the accounting and controlling processes within an organisation for quite a long period of time. Nevertheless, businesses that need more effective insights and integrated processes should consider the SAP S/4HANA Finance possibilities.

The platform makes use of a highly developed data model aimed at ensuring the efficiency and real-time analytics of financial processes. Depending on the chosen version of the solution, the enterprise will be able to manage its general ledger, close processes, profitability and management reporting.

Reasons to migrate:

• Financial insights: Gain access to financial data more quickly for business decision making.

• Reporting simplification: Eliminate duplications in data for the purpose of gaining insights.

• Integrated business processes: Integrate finance with procurement, sales, inventory, etc.

• Process automation: Analyse all processes performed manually and automate them where possible.

 • Future readiness: Make sure the company is ready to adapt its financial processes in the future.

Migration of SAP S/4HANA Finance – Major Steps

1. Understanding of the Current Financial Environment

An important step is an analysis of the existing SAP ECC solution: its finance configuration, customisations, integration points, reporting needs, and data quality. It will allow you to understand what processes work well and where improvements are necessary.

This step will help to understand the scope of migration, the amount of necessary resources and possible risks before you even start the technical part. The expectations about migration from the side of the finance leaders and IT specialists should be clarified.

2. Choosing the Optimal Migration Approach

It highly depends on the existing landscape, business priorities and the willingness to improve some business processes.

System conversion is a migration process when your existing SAP ECC solution is converted to SAP S/4HANA, keeping its configuration to a maximum. New implementation implies creation of a new environment for your company and more possibilities to redesign business processes. Data transition may be useful if you need to migrate only certain business data/historical data.

3. Prepare Financial Data for Migration

The accuracy of information is critical for a successful migration of finance data. It is also important to decide on which historical transactions should be saved, migrated, or available through other reporting options.

Data cleansing and reconciliation should take place before the migration process and not be considered as post-migration tasks. Proper ownership and validation rules will help ensure financial accuracy during the migration.

4. Adjust Financial Processes and Configuration

When moving the finance to S/4HANA, organizations have to assess the financial accounting, controlling structure, reports, and integration needs. The related system pre-requisites and simplifications should be considered with respect to the effect of the Universal Journal on financial processes.

It is also important to analyze any customizations and to evaluate whether they are still required and suitable. When possible, standard SAP solutions may be used instead.

5. Testing of the System before Live Deployment

Tests will ensure that the new environment can perform all necessary financial transactions. Teams of finance and IT need to test the opening balances, account postings, taxation, payments, reports and interfaces with other systems.

Testing needs to consider month and year end closing activities. User acceptance testing will help finance experts make sure that the system is able to meet their obligations.

6. Planning Cutover and Stabilization Activities

Before going live, plan your cutover which should address issues such as data loads, final reconciliations, access rights, interfaces and business approvals. Develop your contingency plans and assign people to solve any critical problems.

Post-deployment, watch financial postings, reports, system performance and user feedback. Solving identified issues in a timely manner will help build confidence in the new system.

Common Issues and Solutions

Even the best planned SAP ECC migration projects may face challenges.

   • Low-quality data: Set rules for cleaning, reconcile the data and assign data owners.

   • Too many customizations: Identify dependency early and plan important development.

   • Disruption to business processes: Plan cutover activities and have a back-up plan.

   • Problems with integration: Test connection to banks’ systems, taxation systems,    procurement systems and others.

   • Change resistance: Provide training according to the role, demonstrate the application and communicate.

   • Uncontrolled project scope: Set milestones, requirements, track changes and approve them.

Early planning and cooperation between finance, IT, compliance and business stakeholders can minimize unnecessary delays.
