SAP Testing with Examples

What is SAP Testing?

SAP Testing is a type of software testing that validates SAP ERP implementations. Any time you change or customize SAP software, fresh test cases must be created to check the new functionality. You also need to retest the SAP system after applying maintenance release notes, OSS notes, or kernel updates. SAP testing can also extend into performance testing (to measure the speed of SAP applications) and web testing (for SAP web portals and Fiori-based interfaces).

Because SAP touches finance, logistics, HR, and supply chain at the same time, even a small configuration change can ripple across many modules. Disciplined SAP testing keeps those ripples from reaching production.

Introduction to SAP

The basic idea behind introducing SAP (System Applications and Products) was to give customers the ability to interact with common corporate databases for a comprehensive range of applications. SAP is an integrated ERP (Enterprise Resource Planning) suite that makes business processes work efficiently across departments and geographies.

The following video explains the need for ERP software like SAP in an enterprise.

The SAP suite contains different modules such as SAP FICO, SD, MM, HR, and more. Each module has its own transaction codes, master data, and customizations, which is why testing strategy is usually planned module by module.

SAP Testing Consultant – a Career Choice

Before looking at how testing is performed, it helps to understand what an SAP testing career actually looks like day to day.

Skill Set	To become an SAP tester you need the following skill sets: Solid testing knowledge (test design, defect lifecycle, automation basics). Functional knowledge of the module being tested (FICO, SD, MM, HR, etc.).
Typical WorkDay	On a typical work day you will be busy understanding requirement documents, creating test cases, executing test cases, reporting and re-testing defects, attending review meetings, and joining team activities.
Career Progression	Your career progression as a software tester (QA Analyst) in a typical CMMI level 5 company will look like the following, though it varies from company to company: QA Analyst (Fresher) => Sr. QA Analyst (2-3 years experience) => QA Team Coordinator (5-6 years experience) => Test Manager (8-11 years experience) => Senior Test Manager (14+ years experience).

How SAP Testing is Better Choice than Testing other Domains?

While testing any AUT (application under test), two things happen:

1. You acquire deep functional knowledge of the AUT. Without enough domain knowledge, meaningful testing is difficult.
2. You hone your testing skills.

As with any IT company, you move from one project to another over time. All the hard work you did to understand one AUT becomes obsolete in the new project. This is especially true when switching domains, say from telecom to healthcare.

With SAP, the functional knowledge you acquire is portable and can be reused across projects. Suppose you are switching jobs. In your old company you tested billing software for a specific telecom carrier. The chance that the same custom system exists in your new company is close to zero.

Now consider this case. You are moving from one SAP testing project to another at a new company. You instantly recognize the GUI, transaction codes, and vanilla business workflows. That is a huge head start. You still need to learn the client-specific customizations, but the core knowledge transfers cleanly.

The biggest advantage of being an SAP Tester is that the deep functional knowledge you build can help you transition into an SAP Functional Consultant role.

SAP Consultants are in high demand and short supply, which is why they often command premium salaries.

What is meant by SAP Implementation?

Consider this scenario. Company A offers 12 annual leaves. Company B offers 20 annual leaves. Salary must be deducted for any employee who takes the 13^th or 21^st annual leave at Company A and B respectively. This information must be configured into the SAP system, which is exactly what SAP implementation and configuration covers.

The SAP vanilla version is powerful but limited in value until it is customized and configured to match business policies, legal stipulations, and technical requirements of a company. This process is called SAP implementation, and it typically takes a few months to several years depending on the scope.

What is SAP Customization?

SAP ships with the largest collection of standard business processes of any ERP. Still, some internal company processes cannot be mapped accurately using the readily available SAP transactions.

In such cases custom code is written using ABAP. Customization involves changing or adding code to create functionality that is not available through standard configuration. SAP customization can also be used to generate custom reports, programs, smart forms, or enhancements through user exits and BAdIs.

What is Maintenance of SAP Software?

Once the SAP system is configured, customized, deployed, and live, any further changes made to it are termed maintenance. Maintenance work typically includes:

• New feature additions to the SAP system.
• Bug fixes for production defects.
• SAP Kernel updates.
• Support Pack and Stack updates.
• OSS note implementation.

Each of these activities can break previously working functionality, which is why every maintenance change must be backed by a regression test pass.

How to do End to End SAP Testing?

There are multiple methodologies that can be used for SAP implementation:

• ASAP Implementation (for initial implementation of SAP systems and porting from legacy systems).
• Maintenance Lifecycle.
• Upgrade Lifecycle.
• Custom Development Lifecycle.

Whatever the lifecycle, SAP testing always passes through three main phases.

1) Test Preparation

2) Test Execution

3) Test Evaluation

Step 1) Test preparation phase

1. Identification of business processes to be tested.
2. Manual and automated Test Case development.
3. Creation of test suites and peer review.
4. Setup of the test system and clients.
5. Creation of test data and master records.

Step 2) Test execution phase

1. Test execution either manually or using test tools.
2. Test status reporting and defect handling.

Step 3) Test evaluation phase

1. Detailed assessment of all test plans and exit criteria.
2. Defect analysis and root-cause categorization.
3. Documentation of the testing process and lessons learned.

Types of Testing Applicable to SAP Applications

Each lifecycle phase relies on different types of testing. The diagram below shows how they fit together in a typical SAP program.

For SAP applications, the common testing types performed are listed below.

1) Unit Testing

Unit testing is mostly handled by developers based on the organization’s Unit Testing rules. It is sometimes performed by skilled white-box testers. The test is run in the development box. It covers interfaces, conversions, enhancements, reports, workflows, and forms (RICEWF) developed primarily with ABAP code. Testing of development objects also includes security authorizations, data transfer rules, reconciliations, and batch scheduling jobs. BW (Business Warehouse) testing is also part of the development tests.

2) Integration Testing

Integration testing checks combined components of an SAP application to determine if they function together correctly. It is typically performed in the QA environment and uses realistic test data, including data flowing through interfaces from non-SAP systems.

3) Regression Testing

Regression Testing ensures that the new changes implemented do not adversely affect the existing working code. SAP S/4HANA and R/3 are tightly integrated systems. A single stack update, OSS note, transport, configuration change, or new development interface can cause severe cascading effects. Regression testing is usually executed using an automation tool by the testing team.

4) Performance Testing

Performance testing checks SAP applications to ensure they will perform well under expected workload. It encompasses load, volume, and Stress Testing to find system bottlenecks. With the goal of strengthening SAP application robustness, this testing confirms systems can manage high load forecasts and prevents performance problems after go-live. Business processes prone to stress due to high transaction or batch volumes are evaluated thoroughly. It is usually executed using automated tools and involves close collaboration of basis, database, infrastructure, and test teams to monitor test results.

5) Functional Testing

Functional Testing ensures that your implementation of SAP meets your business requirements. SAP is highly configurable and can be integrated with in-house applications or third-party tools. Given this varied configuration and complexity, functional testing is a must. SAP functional testing removes uncertainty over business use cases and brings quality. It includes a review of design documents and the creation of test artifacts such as test requirements, Test Scenario, and test cases. Functional testing is usually done by a testing team with a background in the particular SAP module being tested.

6) User Acceptance Testing (UAT)

Once functional, system, and regression testing are completed, UAT (User Acceptance Testing) is performed. It confirms that the SAP system is usable for the end users of the system. The end users independently execute UAT scenarios that include business processes, functions, and documentation (operating manuals, cheat sheets). With UAT, users grow comfortable with the new business environment and can take full ownership of the system.

7) Security Testing

To make sure SAP applications are safe, Security Testing is performed. High-risk areas like SAP Portal security, network security, operational security, product security, access control, and source code audit are tested. This typically involves basis, database, infrastructure, development, and test teams.

8) Portal Testing

This involves testing SAP portals and Fiori launchpads on different browsers and devices, then checking that business processes still complete from end to end.

Manual vs Automated SAP Testing

SAP teams almost always blend manual and automated approaches. The table below summarizes how the two compare across the dimensions that matter most on real projects.

Dimension	Manual SAP Testing	Automated SAP Testing
Best fit	Exploratory testing, UAT, one-off configuration checks.	Regression, performance, repeat smoke tests across releases.
Setup effort	Low. Tester needs only access and a test plan.	Higher. Scripts, frameworks, and test data must be built first.
Execution speed	Slow. Each pass repeats the same clicks.	Fast. Hundreds of cases can run overnight.
Coverage	Limited by tester time and fatigue.	Broad once scripts are written and maintained.
Maintenance	Test cases stay valid as long as the process does not change.	Scripts must be updated when transactions, screens, or fields change.
Common tools	SAP GUI, HP ALM, spreadsheets, Jira.	eCATT, SAP TAO, OpenText UFT One, Tricentis, testRigor.

How to Create a SAP Test Case

Let’s design a test case to change the name of an employee in an SAP system.

To create an effective test case, you must:

• Determine the SAP role required to execute the test case.
• Identify the SAP transaction that needs to be executed for the test case.
• Decide the test data required to execute the test case. Decide whether the data needs to be created, whether it is shared with another tester, or whether the data is locked and cannot be modified.
• List any pre-requisites such as open posting periods or active employee status.
• Peer-review the test cases before execution.
• Create positive as well as negative scenarios.
• Write detailed, step-by-step test steps.
• Make sure test coverage is robust across positive, negative, and boundary cases.
• Document defects in a timely manner, as soon as they are discovered.

Refer to this video for a guideline on how to change an SAP Infotype.

The test case designed for this is shown below.

Important Note

SAP is an enormous system with endless variations. It is neither feasible nor cost-effective to check all possible variations and combinations of test parameter inputs.

As in the SAP test case example above, a tester could have verified change in Last Name, Date of Birth, Address, Pin Code, City, State, Country, change in permanent, temporary, work address, and more.

A tester needs to adopt strategies to reduce the number of test cases without sacrificing coverage. Examples of such strategies include boundary value analysis, equivalence partitioning, and orthogonal arrays.

Automated Testing of SAP Applications

Testing is a huge challenge for a colossal system like SAP. According to a recent ASUG study, over 86% of customers are concerned about risks caused by a lack of comprehensive testing.

Automation has the following benefits for SAP applications:

1. The chief and most valuable benefit is improved test coverage.
2. Better product quality and therefore fewer production outages. Outages in SAP production environments can cost a company millions per hour.
3. Workload decreases with each release cycle once the regression suite is stable.

SAP TAO automates the generation of test components for end-to-end scenarios. The SAP TAO and HPQC setup carries some benefits over other testing tools because of the broad corporate support for HP and SAP software products.

The SAP TAO client application performs three functions: inspecting transactions from an SAP server, exporting the transactions to HP Quality Center, and consolidating components or scripts from HP Quality Center.

Performance Testing of SAP Application

Performance testing of SAP applications is done to check speed, scalability, and stability. Performance testing on SAP helps with:

• Conforming with service-level agreements (SLAs).
• Optimizing software configuration settings.
• Reducing overspending on hardware.
• Certifying that the system will not crash or fail during seasonal high load and avoiding the financial losses that come with it.

Events that Trigger Performance Test

The choice of performance testing tool for SAP depends on the underlying SAP application being tested. Below is a list of SAP performance test tools and their application areas.

1. Open source / Free

• JMeter – performance test SAP BusinessObjects BI Platform.
• Open STA – performance test SAP Portals.

2. Commercial

• LoadRunner – performance test SAP ECC among other SAP applications – recommended by SAP.
• IBM Rational Performance Tester – can test a wide variety of SAP applications.

Pick a tool that already supports the protocol your SAP application uses (SAP GUI, HTTP, RFC, ODATA) so you do not spend weeks building protocol adapters before the first script runs.
