• Add extensions to standard processes
• Add customer-specific data within SAP Best Practices content SAP Central Business Configuration is a tool that allows you to configure and customize your SAP S/4HANA Cloud solution using predefined content and settings.

The changes that would prevent SAP from running automated business process tests on your behalf are:

• Configuration changes that impact the process flow
• Changes to the data input requirements (custom data fields) These changes would require manual adjustments to the test scripts or data sets to ensure that they match your customized solution. SAP-made changes to the standard test process or changes to the SAP S/4HANA Cloud release (upgrade) do not prevent SAP from running automated business process tests on your behalf, as they would be reflected in the predefined test content.
