In the Fiori App Manage Service Entry Sheets - Lean Services (F2027), when entering the Service Performance Period outside the period of the Start and End date of service entered in Purchase Order, error message "The service performance date is outside the period of performance" (MM_PUR_SES 015) is triggered.
