Currently, am having to do analysis regarding replacing a third party system which calculates client's payroll with SAP ERP.
Customer already has SAP HR, basic infotypes and sends relevant master data to third party for payroll including , but it does not have a planned working time infotype but a similar client infotype 9**** which is the Planned working time infotype.
Would we need the standard 0007 infotype to do the time and payroll calculation in SAP if we replace the third party system?
