SAP Testing - Interfaces


An Interface in an ERP system is known as a tool that is responsible to get data from one system and move that data to another system. For example, assume you have a program that produces a report in XML format and then this program reads the XML file to provide input to another system. You can also manipulate while passing the information from one system to other.


Consider a vendor tool that takes care of employee attendance. Now, the system interface will take this information and populate it in the SAP HR system.

Interface testing ensures that this job is running successfully to ensure that the data is transferred completely and there is no error while transferring the data to the SAP HR system.
