Can you show the initial screen of PC00_Mxx_CALC? Also, as asked by Praneeth, please check the master data thoroughly, that the same exists for the period in which you want to run the payroll or not. Only entering Payroll Area does not counts for payroll run. Master Data must exists for the period payroll is being run, also employee must exists in the payroll area during the period.
