I saw the P&F based applications delivered with the new HR Admn Role (SAP_ASR_HRADMIN_SR_HCM_CI_4) and they are all OVP based. The Start Process uses ASR_PROCESS_START_OVP and there is the handy Open Processes (ASR_PROC_BROWSER_OVP).
I thought I read somewhere that similar feature would be available with MSS as well. However, I checked both MSS Roles (UI5 and the regular *NWBC_3), but both did not have the Open Processes Application at all. Also the Start Process still is ASR_PROCESS_EXECUTE_FPM and not OVP.
Were the OVP applications not scheduled to be part of the MSS Role? Please let me know if I am not looking in the right place.
