In SAP, the employee enters this task and performs further actions related to its completion. Once the domestic invoice is posted, the employees will exit SAP and go to Harmodesk where they will report the completion of the domestic invoice posting as "completed" (simple posting).
This way, Harmodesk collects data on times of completion of every task your employees perform. With detailed data and reports, you'll know exactly what they're spending their working time on. Is the posting in SAP already completed?
