Hi Sai,
i am working on UK GB payroll, so if i am updating HRSP then i will be looking for GB legal changes like Statutory, RTI & so on
like this you have to specifically look for country specific changes , i think you are working for US payroll then you have to look for US payroll related changes
please take a back of Table T512W - this is very useful have a look at the below link
Backing Up Table T512W - ERP Human Capital Management - SCN Wiki
please dont forget to run the payroll in live for different EEs groups & also try to post them while testing them
Regards
Rahul
