SAP Process Automation combines the capabilities of the SAP Workflow Management and SAP Intelligent Robotic Process Automation services, in one product where “citizen developers” can easily automate processes themselves. Business users can use visual tools – like the Form Builder and Decision Tables – without coding to automate workflows and processes, while developers can build add-ons and extensions for the business user.
