SAP Testing - Modules
There are different SAP modules implemented in an organization that can be tested using various testing tools like HP Quick Test Professional (QTP), IBM Rational Functional Tester (RFT), and SAP Test Acceleration and Optimization (TAO) tool.
Common SAP Modules
The common SAP modules are listed below −
Financial Modules − Finance Accounting and Controlling (FICO), Treasure (TR), and Enterprise Control (EC).
Logistics Modules − Material Management (MM), Plant Maintenance (PM), Sales and Distribution (SD), Quality Management (QM), etc.
Human Resource Management − Accounting Payroll, Time Management, Training and Event Management.
All these modules are inter-dependent and the functionality of one module affects the functionality of other modules.
Suppose you have to create a Sales Order in Sales and Distribution (SD) module. Here, you first need to enter the transaction code(e.g., Transaction Code VA01). Next, check the stock of the item in Inventory module and check the credit limit available on Customer profile in Customer Relationship Module. It shows that all these modules are interdependent; if you customize any of these modules, it will affect the related ERP system.
To perform SAP testing, you need to understand the features, functionalities, and how the workflow takes place in these SAP modules. Most of the common reasons of failure of ERP implementation project is incorrect test planning and the use of wrong test-cases.
Non SAP ERP systems like PeopleSoft, Edwards, Oracle E business suite have different customers and capabilities. The testing team needs to understand the functionality of complete system.
Types of Testing Team
There are normally two types of testers available in SAP projects −
Core Testers − who are responsible to perform basic testing of ERP system and modules.
Implementation Testers − who work on implementation project and cover the customization functionalities of SAP modules.
Customization requests from clients can impact the modules of a SAP system. The testing team should be able to record each customization request and its impact on the other SAP modules.
ERP systems are large systems and therefore the testing process should ideally be automated. It is always advisable to perform automated testing for ERP systems, as manual testing is a very time-consuming and lengthy process. Without testing each component of the SAP system, it is really tough to achieve 100% quality and successful implementation of SAP project.
Performing SAP testing for the above example using QTP
To perform SAP testing for the above example, follow the steps given below −
The first step is to install HP QTP tool and to install necessary plug-ins within QTP to make it compatible to connect to ERP system.
The next step is to use HP Quality Center (QC) to develop the test plan and then to convert test plan design to Test Scripts. These test plans can be converted to scripts using HP QTP.
Next, record the R/3 GUI screen of SAP system for SD module while creating Sales Order or creating PR in MM.
After you are done with the recording in QTP tool, create a script in VB.
SAPGuiSession("Session").SAPGuiWindow("SAP Easy Access - User") .SAPGuiOKCode("OKCode").Set "/nVA01" SAPGuiSession("Session").SAPGuiWindow("SAP Easy Access - User"). SendKey ENTER
You can also add different parameters and customizations as per your requirement.
