An SAP S/4HANA migration is a massive undertaking. It promises a faster, smarter, and more integrated future for your enterprise. But while your IT team is heads-down orchestrating this complex digital transformation, what happens to your e-procurement system operations? For many organizations, the answer is that they grind to a halt.
This doesn’t have to be your reality. You can keep your e-procurement system running at full speed throughout your S/4HANA journey. The key is to avoid common pitfalls that derail procurement during the transition. This guide will walk you through five critical mistakes and show how a modern, unified e-procurement layer like Vroozi ensures business continuity and sets you up for success.
Mistake 1: Treating Procurement as an Afterthought
One of the most frequent errors in migration planning is involving the procurement team too late. IT often leads the charge, focusing on the core technical aspects of the ERP cutover. By the time procurement leaders are brought into the conversation, critical architecture and process decisions may already be locked in, limiting the ability to support procurement’s unique workflows and UX needs.
This oversight can lead to a solution that doesn’t meet the real-world needs of buyers, creating adoption issues and inefficiencies down the line.
Solution: Engage Procurement Leaders Early and Often
The most successful S/4HANA migrations treat procurement as a strategic partner from day one. Involve procurement leaders in the initial planning phases to define clear requirements for your e-Procurement system. This parallel planning ensures that both IT and procurement are aligned. Procurement can identify which workflows are non-negotiable and must remain active, while IT can architect a migration strategy that supports those needs without causing disruption.
Mistake 2: Pausing or Slowing Procurement Workflows
When IT freezes changes to the legacy SAP ECC system to prepare for migration, procurement workflows are often the first casualty. Approvals, new orders, and supplier onboarding can stall for weeks or even months as the technical team focuses on the cutover. This isn’t just an inconvenience; it’s a direct hit to your company’s bottom line and operational agility.
Solution: Maintain Full Functionality with a Unified Procurement Layer
A unified procurement platform like Vroozi provides a consistent interface for users to manage requisitions, catalogs, approvals, and invoices—even as the underlying ERP shifts from ECC to S/4HANA.
Mistake 3: Relying on Customizations That Don’t Transfer to S/4
Over the years, many organizations have built extensive customizations into their SAP ECC systems to meet specific business needs. While these custom workflows might work today, they often become a major roadblock during an S/4HANA migration. Much of this legacy code is fragile, poorly documented, and not easily transferable to the new S/4HANA environment. Recreating these customizations is both costly and time-consuming.
Solution: Replace Customizations with Configurable, S/4-Ready Tools
Instead of trying to rebuild fragile custom code, use the migration as an opportunity to standardize and simplify. A modern procurement platform offers out-of-the-box, configurable workflows that can replace most legacy customizations out of the box. By integrating via the SAP Business Technology Platform (BTP), solutions like Vroozi provide a clean, certified, and future-proof connection to S/4HANA. This approach reduces technical debt and gives you a more agile, scalable e-procurement system.
Mistake 4: Neglecting User Adoption and Training
Change is hard. When employees are suddenly faced with a new, unfamiliar interface after the S/4HANA go-live, adoption can plummet. If the new system is difficult to navigate, users will quickly revert to old habits, like making off-contract purchases or sending procurement requests via email. This “rogue spend” undermines the very visibility and control that the new ERP was meant to provide.
Solution: Provide a Consistent, Consumer-Like Interface
An intuitive user experience is the key to high adoption. By implementing a unified procurement layer before the migration, you give your users a simple, consistent interface that doesn’t change, even when the back-end ERP does. Platforms like Vroozi offer a familiar, Amazon-like marketplace experience that requires little to no training—leading to higher user adoption and fewer support tickets.
Mistake 5: Losing Visibility into Spend and Supplier Performance
During an ERP transition, data can become fragmented. With some information in the old ECC system and some in the new S/4HANA environment, generating comprehensive spend reports becomes nearly impossible. This lack of visibility means procurement and finance leaders are flying blind. They can’t track spending against budgets, monitor supplier performance, or identify new savings opportunities.
Solution: Keep Data Centralized for Uninterrupted Analytics
A unified procurement layer ensures that all your procurement data—from requisitions to invoices—remains centralized and accessible throughout the migration. Because all purchasing activity happens within the platform, you maintain a single source of truth for spend and supplier data.
Reporting and analytics continue uninterrupted, giving you the real-time insights needed to make strategic decisions, manage budgets, and maintain financial control before, during, and after your S/4HANA migration.
