1. What Is the SAP FUE Model?

SAP's Full Use Equivalent (FUE) model represents a significant shift in how software usage is licensed and measured across SAP environments. Unlike traditional models that charge per named user, the FUE model introduces a more flexible and role-based licensing approach. This model is especially relevant in the context of cloud-based solutions like RISE with SAP, where users may interact with multiple systems and perform various business functions.

In the FUE model, licenses are assigned based on predefined user personas, each of which reflects a typical set of business tasks and responsibilities. Common examples include: Business User, Developer, Professional User, or Self-Service User. Each persona corresponds to a weighted FUE value. A Developer might count as 5 FUEs, whereas a Self-Service User might count as 0.033 FUE. The total number of FUEs directly determines the final license cost.

The real cost range: For an organization with 1,000 users, total licensing costs could range anywhere from €66,000 to €2,000,000 per year, depending entirely on how users are classified. Whether you're in Germany, Poland, or Spain — FUE classification has a direct and potentially dramatic impact on your SAP licensing bill.

2. Why SAP Introduced FUE

The FUE model was introduced as part of SAP's broader move toward cloud-based, subscription-driven licensing — particularly under RISE with SAP. Traditional SAP licensing was based on named users and specific system access, but this model struggled to keep up with the increasing complexity of digital transformation and hybrid IT landscapes.

SAP introduced FUE to align licensing with business processes rather than technical system access, and to simplify subscription licensing across the SAP ecosystem. However, in practice, SAP's licensing criteria include over 2,000+ lines of authorization value definitions and more than 700 authorization objects that determine when and what type of license should be assigned.

3. FUE Is Not Just a Formal Change

At first glance, the FUE model may seem like just a new way of counting users. But this is a serious misconception. FUE represents one of the most significant shifts in SAP's licensing model in decades. It no longer matters how many users you have — it matters what each of them is technically capable of doing in the system.

SAP now calculates license usage based on: the activities a user can perform (create, display, approve, post), the authorization objects and values assigned to their roles, and the business persona that best matches their system behavior.

Example: The Cost of Business Partner Access

Let's say a user has access to transaction BP (Business Partner) to view customer records. If they only have display rights (Activity 03), they might fall under a Self-Service User license. But if their role includes create (Activity 01) or change (Activity 02), they may be classified as a Core or even Advanced User — even if they never use those functions. Multiply this logic across dozens of roles and hundreds of users, and the financial impact becomes clear.

SAP Note 3113382: The Official Simulation Tool

SAP provides a simulation report (SLIM_USER_CLF_HELP) via Note 3113382 that estimates FUE consumption based on current authorization assignments. The ruleset includes over 700 authorization objects and 2,000+ conditions. SAP itself recommends supplementing it with their expert STAR service — indicating that the tool alone is not sufficient for licensing strategy without manual effort.

4. The Role of GRC Tools in Managing FUE

With the FUE model, GRC is no longer just about internal controls or audit readiness — it's now also a key enabler of cost-effective licensing. What a user can technically do in the system directly impacts which license tier they consume. Without continuous visibility and control over role assignments, organizations risk both compliance failures and unnecessary licensing costs.

GRC tools fill the operational and strategic gaps by:

5. Summary

SAP's FUE model is not just a new way to measure licenses — it's a fundamental change in how access, cost, and compliance intersect in the SAP landscape. It shifts the responsibility onto customers to understand, monitor, and justify each user's access with precision.

Organizations that treat FUE as a formal checkbox risk paying 2–3× more than necessary, assigning licenses based on theoretical access rather than actual business need, and losing control of their licensing strategy entirely.

The organizations that succeed under FUE will be those that integrate GRC thinking into their licensing strategy, and treat access not only as a security risk — but as a cost driver that can and should be optimized.
