There is an easy way to run time evaluation in parallel. Standard PT60 doesn’t know anything about it and you need to wait a long time everytime you run payroll for all your employees.
A long time ago SAP developed this program, that nobody knows about – RPCS0000 to schedule background time evaluation in parallel.
The program allows reducing runtime evaluation in parallel in background split by a group of personnel numbers. It dramatically reduces runtime for the whole company, particularly when you have thousands of employees.
