We are having SAP Certified Biometric interface which reads Time In and Time Out at plant location. We need time data should be processed through Time Evaluation and then it should go for Approval to Manager. If it's overtime then it should be approved at the same time by manager. Employees are not expected to fill time sheet /CATS .
I've referred below links before posting this query but didn't get answer.
Kindly suggest the best possible approach for designing the solution.
