SAP Testing Interfaces

What is an interface?
An Interface in an ERP system is a tool to transfer data between systems. For example, say there is a program that produces a report in XML format. Then this program reads the XML file to provide input to another system. You may manipulate while passing the information from one system to other.

Ex:
Consider a vendor tool that takes care of employee attendance. The system interface will take this information and populate it in the SAP HR system. Interface testing ensures that this job is running successfully. It ensures that the data is transferred completely and there is no error while transferring the data to the SAP HR system.

SAP Interface Testing:
SAP Interface testing is purely dependent on the operations and organizational processes. The following points are to be considered while performing SAP Interface Testing:

• Understand the purpose of using SAP Interface and the business scenarios which are processed by the interface
• Check if the Interface is processing all business scenarios accurately as per the test strategy.
• To perform Interface testing, the best practice is to start with performing Unit testing.
• Check if the outbound interface is performing well. Ensure the file meeting specifications in terms of layout, etc are performed.
• Check if the inbound interface is running well. Ensure that the file is read correctly and performs the correct steps in the target system.
