We are currently running our payroll and time on SAP using negative time (i.e., capturing only time exceptions) for our production and packaging people). We are looking at switching this group of employees to positive time and implementing a timekeeping software to capture time and interface this with SAP for payroll processing. What are the high level cost and effort estimates we would be looking at to implement the timekeeping software? Also what are the high level changes that would be needed on our SAP system to make this work? I would appreciate any inputs from those who have done a similar set up.
