Why Testing SAP Was So Difficult
Extremely complex IT landscape:
Over 2000 non-SAP applications created massive interdependencies across the enterprise.

Dependency on external teams:
Testing couldn't progress unless development and test teams of 3rd party systems were also ready.

Asynchronous priorities:
3rd party teams worked in different sprints — delaying or derailing SAP S/4HANA testing phases.

Risk of poor coverage:
Limited test access often led to delays, missed bugs, and incomplete validation of key business flows.

The Solution
Service Virtualization That Removes Barriers and Accelerates SAP Projects
Simulate to Remove Delays
Int4 Messenger virtualizes all non-SAP systems so SAP test phases can run independently of external teams or system availability.
Reduce Testing Costs
By simulating third-party systems, you eliminate the need to set up and maintain costly test landscapes and external dependencies.
Catch Issues Early
Enable your development and functional teams to test early and often — detecting bugs sooner and preventing go-live surprises.

The ability to increase manual testing speed of a complete SAP business process without being dependent on the 3rd party, non-SAP systems secured the testing phases and increased the level of developed and configured SAP S/4HANA processes.

Solution Impact
Why Service Virtualization Was a Game-Changer
With Int4 Suite, our client replaced dependency-heavy processes with fast, independent testing — enabling earlier defect detection, cost savings, and project acceleration.
Remove Testing Delays
Simulate third-party systems and unblock every test phase without waiting on external dependencies.
Cut Infrastructure Costs
No need to spin up and maintain heavy, costly landscapes for each connected system.
Boost Confidence and Quality
With more tests, run earlier, developers and SAP functional teams catch defects faster and ship with confidence.
Simulate to Remove Delays
With Int4 Messenger, 3rd party non-SAP systems can be fully virtualized, enabling complete SAP S/4HANA testing without external dependencies. Here's how our customer achieved seamless, delay-free execution.
Cost Efficiency
Reduce Infrastructure Costs Through Virtualization
By simulating non-SAP systems instead of maintaining costly test landscapes, SAP teams can dramatically lower infrastructure costs.
Service virtualization with Int4 Suite removes the need to deploy and support 3rd party systems just for testing — making your S/4HANA project more sustainable and efficient.

Strategic Impact
Why Service Virtualization Matters for SAP Testing
When testing SAP systems, waiting for support from 3rd party teams can delay progress and reduce coverage. Virtualization eliminates this bottleneck.
By simulating external systems, your SAP developers and functional consultants gain the freedom to test anytime — detecting issues early and reducing production bugs.
