The 'actual duration' recorded in an SAP S/4HANA service confirmation is fundamental for several integrated processes. Its primary purpose is to capture the technician's actual working time for a service task (A). This time data is then used to calculate and post internal labor costs to the service order via activity allocation in the Controlling (CO) module (D). Additionally, the system can be configured to automatically create an entry in the Cross-Application Time Sheet (CATS) based on the confirmed duration, streamlining time management for HR and payroll (C). These functions represent the direct use of the confirmed time within the system.

B. Updating the technician’s capacity: The confirmation records the consumption of a technician's capacity for a specific task, but it does not update their master data regarding total available capacity.

E. Calculation of the customer price: The confirmation provides the quantity (duration) for billing, but the actual price calculation using sales conditions occurs in a subsequent document, such as a billing document request.

3. SAP Training Courseware - S4700 (Service in SAP S/4HANA): The official course materials for the certification exam detail the service confirmation process. Unit 5

"Service Execution

" explains that confirmations trigger activity allocation for internal costing (CO integration) and can be integrated with CATS (HCM integration). It also distinguishes the confirmation step from the subsequent billing step where customer pricing is applied.
