SAP Screen Personas serves to increase the productivity of users of an SAP system by simplifying and personalizing SAP S/4HANA and SAP ERP Dynpros and Web Dynpro ABAP screens. For example, data and screen elements can be hidden process-related and fields can already be pre-filled with data to simplify the work for the user.
A central component of the SAP user interface strategy is the SAP Fiori UX. SAP Screen Personas allows you to apply Fiori UX to customer transactions or standard transactions and, most of the time, to modernize transactions based on Fiori UX. So that old transactions fit seamlessly into the Fiori Launchpad.
Also, SAP Screen Personas uses the Slipstream Engine to render dynpros on mobile devices in SAPUI5 style.
