In today’s market, ERP plays an immense role in the success of medium and large enterprises. All businesses rely on ERP software to carry out their daily operations and enhance business workflows.
Implementing these systems is not easy, especially if you are using SAP, one of the most advanced ERP solutions in the market. One must configure the different SAP modules to deliver the relevant features. So an implementation of any SAP module requires some kind of testing. In this article, we will discuss what SAP testing is and explain its importance.

What Is SAP?
Before learning about what SAP testing is, it is necessary to understand what ERP software is and how it works.
ERP is a comprehensive software solution that offers advanced and extensive features for managing different business processes, such as production, manufacturing, logistics, distribution, finance, CRM, sales, human resources, etc. It contains several interconnected modules, and data can be shared seamlessly between them. This interconnected system allows us to eliminate data redundancy and efficiently utilize available resources across different departments and business processes.
SAP (Systems, Applications and Products) is considered one of the most popular ERP (Enterprise Resource Planning) solutions used across most Fortune 500 companies. SAP software enables organizations to manage business processes efficiently and minimize operational costs. Unsurprisingly, it has a wide application across different industries.
To perform testing effectively in SAP or any other ERP solution such as Oracle EBS, Odoo and PeopleSoft, one has to understand how their modules, features, and functionalities work.
What Do You Mean by SAP Testing?
When we speak about SAP testing, we mean testing different modules of the SAP ERP software. Every module supports a particular business process: finance, accounting, sales, etc. Default versions of these modules often lack features specific to a particular company’s business needs, so business users usually want to customize these basic modules. And when customization is done, companies need to ensure that the system works properly and meets user demands.
That is why SAP testing is necessary. Without proper SAP testing, an ERP module is bound to get rejected by customers. And the reason behind the repetitive failure of SAP ERP projects is that developers don’t usually perform the testing activity efficiently.
Even after a solution is implemented successfully, it requires constant updates such as new module implementations or bug fixes. All of these updates also have to be tested. Therefore SAP testing must be an ongoing process in any company that uses this solution.
Testing of Different SAP Modules
Every SAP module (or any ERP module) is a set of functionalities and features developed for a specific business process or organizational workflow. For example, you may have a separate accounting module, which supports all necessary for your team accounting features. You may also have different modules for sales, finance, inventory management, procurement, and so on. In many cases, these modules are interdependent. For instance, an accounting module will gather data from several different modules: procurement, sales, inventory management, and even data from manufacturing and human resources.
SAP testers typically break down SAP modules into two different categories: technical modules and functional modules. It’s important to integrate both of them to help businesses run smoothly. For example, Payroll module is a technical module where we manage employee attendance, personnel management, and payroll process. However, companies can group these technical modules into a single functional workflow under Human Resource Management.
Different Types of Testing for SAP Suite
Unit testing is the type of SAP testing where testers check whether functions or subroutines of a single module are working properly on their own. It is a form of white box testing and used for testing interfaces, conversions, workflows, forms, reports, security authorization, and data transfer rules within the system.
This kind of testing must be performed by skilled developers who have in-depth knowledge of each component’s functionality.
SAP applications are known for their high configurability. They even support integration with third-party applications. SAP integration testing allows one to ensure that all SAP modules work correctly after being integrated.
In integration testing, testers evaluate how SAP modules components interact with each other after being configured into a single SAP system. Testers also check each module’s workflows, interface triggers, as well as reports. So as a result we can be sure that the system’s components interact successfully and the whole system follows the correct data flow.
Typical SAP system is being constantly updated. Its configuration changes with any new feature or interface component implementation. And because system modules are interconnected, even minor glitches in one module can have adverse consequences for the entire system. That is why regression testing is extremely important to deliver high-performing software. It helps us to see whether new features have some unforeseen impact on the software.
Skilled testers carry out SAP regression testing with powerful automation tools. Doing so prevents unexpected changes to system functionalities and ensures that core business processes can run seamlessly.
Performance testing is used to understand how the system components are performing in a given situation. It allows to check system reliability, scalability and resource usage. These benchmarks act as a metric of performance for a given module. If the module responds to generated requests in the given range, it meets the given benchmark. If it fails to do so, we need to identify the source of the performance issues.
These are some of the steps we should follow in SAP performance testing:
● Test if the module or collection of modules meet user requirements
● Determine if the collection of modules can support the expected concurrent user load
● Evaluate whether periodic processes are executed within permissible time
● Identify bottlenecks arisen as a result of high transaction rate, inefficient coding, or batch volumes
User Acceptance Testing
In user acceptance testing customers use software components to see if they meet their requirements. They can ask the development team to make further enhancements to the product if necessary. This final interaction with end-users and stakeholders can ensure that all the agreed-upon requirements are a part of the product.
In security testing, we examine application components potentially at most risks. This means we must ensure operational security, product security, network security, portal security, ensure access control, and perform source code audit. This kind of testing can be performed by different team members: experts in infrastructure, development, database, and of course, testers.
Security Testing helps us ensure the safety and integrity of SAP modules. Without security testing, we can’t make sure that SAP users have access to necessary data and transactions they need.
As an ERP, SAP systems have several portals based on a client’s requirements and business processes. Portal testing is necessary for ensuring that portals operate without errors on different browsers.
SAP Testing at Performance Lab
SAP systems are an array of complexly designed and interconnected modules. SAP testing is extremely necessary for the integration and performance of SAP applications and modules. Since SAP applications are the lifeblood of large scale enterprises, even minor errors in one module can have catastrophic consequences for your clients. This is why we recommend professional testing services for all our clients. Performance Lab is a software testing company with deep expertise in providing in-depth testing for SAP systems, across multiple modules such as finance, healthcare, accounting, and other enterprise applications. Our knowledge and professional experience help us find hidden issues in the SAP modules and ensure that every module works seamlessly.
