Payroll isn’t just a back-office function — it’s the lifeblood of employee trust and operational efficiency. But for many enterprises still relying on SAP ERP HCM, the cracks are beginning to show. Whether it's outdated interfaces, manual dependencies, compliance nightmares, or a lack of integration flexibility — the limitations are no longer tolerable.
With SAP announcing the end of maintenance for its on-premise HCM by 2027, organizations face a pivotal question: How do we move forward — securely, smartly, and with minimal disruption?
Enter SAP SuccessFactors Employee Central Payroll (ECP) — a modern, cloud-based payroll solution designed to meet the demands of global businesses. But migrating to SAP SuccessFactors ECP is not just a plug-and-play affair. It comes with real-world challenges — data complexity, process reengineering, integration hurdles, and change management.
In this blog, we unpack those complexities and present practical, real-world solutions, enriched by DynaTech’s migration expertise. Whether you're at the exploration stage or preparing for a full rollout, this blog is your blueprint to understanding what lies ahead — and how to get it right.
As enterprises scale across geographies, adapt to ever-changing labor laws, and digitize HR workflows, the rigidity of legacy systems like SAP ERP HCM becomes a liability rather than an asset. While the platform served well for years, its architecture simply wasn’t built for the cloud-first, employee-centric world we operate in today.
Moreover, SAP has announced mainstream maintenance for SAP ERP HCM will cease in 2027, followed by restricted support for select customers till 2030 via SAP HCM for S/4HANA. This limited extension is not a long-term strategy — it’s a transitional buffer. Businesses that continue to delay migration risk falling behind on compliance, innovation, and operational efficiency.
Here’s a quick breakdown of where SAP ERP HCM falls short today:
| Aspect | SAP ERP HCM | SAP SuccessFactors ECP |
| Deployment | On-premise only | Cloud-native |
| Maintenance | Ends 2027 (core HCM) | Continuously updated with innovation |
|
Compliance Handling |
Manual updates needed | Automatic global/local compliance updates |
| Integration | Complex, limited external integrations | Pre-built integrations (SAP & non-SAP systems) |
| Scalability | Difficult to scale across multiple regions | Scalable for global payroll operations |
| User Experience | Outdated interface | Modern, employee-centric UX |
| Real-time Insights | Limited reporting capabilities | Embedded analytics and real-time dashboards |
| Cost Model | High CapEx (infrastructure, upgrades, maintenance) | OpEx (subscription-based, lower IT overhead) |
While both SAP HCM and SuccessFactors come from the same vendor, migrating between them is far from a simple switch — it’s a strategic transformation impacting every payroll layer. But in practice, it’s a complex transformation that touches every layer of payroll architecture, from data models and localization to integrations and organizational alignment.
Let’s walk through the five most common technical and business challenges enterprises face during this transition — and the best ways to overcome them.
Legacy payroll systems are often bloated with years — sometimes decades — of unstructured, incomplete, or redundant data. This poses a huge risk during migration, especially if organizations try to “lift and shift” everything to the cloud.
Solution:
DynaTech recommends a phased data cleansing approach before migration. Our phased approach mitigates risks associated with data integrity, ensuring clean, accurate payroll processing from day one. This includes:
We also use pre-built data quality templates tailored for SAP ERP HCM to SuccessFactors ECP transformations to accelerate validation processes.
Enterprises typically run complex ecosystems — time tracking, benefits administration, finance, and third-party tools (like Workday, Kronos, or Salesforce). Integration challenges emerge when these tools must now interface with SuccessFactors Employee Central Payroll (ECP) in real time.
Solution:
DynaTech leverages SAP Integration Suite, SAP BTP, and bespoke APIs to build secure and scalable middleware between SAP SuccessFactors ECP and external applications. We also conduct interface simulation tests to ensure real-time syncs don’t break under load.
Bonus: Our D365 API connectors and eCommerce integrations can be configured to work in hybrid ERP environments — a huge win during staggered migrations.
ECP supports over 45+ countries natively, but many multinational organizations operate in countries that require custom compliance rules, collective labor agreements, or specialized tax logic.
Solution:
DynaTech has built a Global Payroll Localization Framework that:
We also support dual-run simulations to validate calculations before go-live.
Payroll is mission-critical. Even a one-cent error can trigger distrust, audits, or worse — delayed salaries. Testing the new system against old records (parallel run) is complex, time-consuming, and error-prone without the right tools.
Solution:
DynaTech uses automation-based parallel run testing tools that:
We also offer managed services for post-go-live payroll validation — especially during the first 2-3 payroll cycles.
ECP comes with a new interface, logic, workflows, and reporting style. For organizations used to on-prem HCM, this shift can confuse users and increase ticket volumes post-go-live.
Solution:
DynaTech delivers custom enablement programs, which include:
We also integrate chatbots and Power BI dashboards to simplify self-service access to payroll summaries and payslips.
What makes SAP SuccessFactors Employee Central Payroll (ECP) a true game-changer isn’t just its cloud-native infrastructure — it’s the range of built-in features that streamline payroll operations, enhance compliance, and elevate the employee experience.
Let’s explore the key features of SAP SuccessFactors ECP that set it apart from traditional systems and alternative cloud solutions.
With out-of-the-box support for 45+ countries, ECP handles global compliance natively. It ensures that local labor laws, tax structures, and social security rules are built-in and regularly updated — a major leap from the manual compliance processes in SAP HCM.
Automatic legal changes and configuration updates
Because ECP is an extension of Employee Central, it shares a single source of truth with the broader HXM suite. Any changes in employee status, benefits, job info, or time records in EC are reflected in payroll — instantly.
Using Payroll Control Center (PCC), admins can proactively monitor payroll processing in real time. PCC offers:
From statutory reports to internal KPIs, ECP comes with advanced analytics options like:
Built on SAP’s Business Technology Platform, ECP offers:
Making the move from SAP ERP HCM to SuccessFactors ECP isn’t just about modernizing infrastructure — it’s about unlocking real business value. Here’s what enterprises gain by migrating to SAP SuccessFactors ECP:
Thanks to automation, real-time validation, and seamless EC integration, payroll cycles are reduced by up to 30–40%, enabling faster payouts and fewer delays.
With built-in legal updates, audit trails, and GDPR-compliant data practices, ECP helps mitigate risk, especially in multi-country operations.
While initial migration has costs, ECP’s cloud model eliminates server maintenance, upgrades, and downtime — leading to 20–25% lower IT overhead over 3 years.
Combine payroll and workforce data for real-time dashboards, insights, and cost forecasting — especially powerful when enhanced with DynaTech’s BI solutions.
As business grows, ECP scales without re-implementation. New geographies? New compliance rules? The platform evolves automatically
| Benefit | Impact |
| Payroll Cycle Time | ↓ 30–40% |
| TCO over 3 Years | ↓ 20–25% |
| Payroll Errors | ↓ up to 60% |
| Reporting Speed | ↑ 3x faster |
With these benefits, companies aren’t just catching up — they’re pulling ahead.
