According to the SAP S/4HANA Cloud, public edition Learning Journey1, some changes that would prevent SAP from running automated business process tests on your behalf are: changes to the data input requirements (custom data fields); configuration changes that impact the process flow. Automated business process testing is a feature that allows you to test your business processes and scenarios in SAP S/4HANA Cloud using predefined test scripts and data. Changes to the data input requirements or the configuration settings may affect the validity or execution of the test scripts and data, and therefore require manual testing or adaptation.
