interface to SAP

Hi All

Our client is using third party tool to run the payroll. SAP Payroll also they are using in parallel and comparing the results.

They would like to use the Third party tool rather than SAP payroll, since third party tool is more compatible with their country payroll.

They have decided to go with third party payroll.

But posting to Finance they want to do from SAP.

Therefore they want a interface from third party to SAP, to transfer the payroll results from third party to SAP tables. So that posting should happen from SAP HR to FI.

So any suggestions on how to make the interface from Third party tool to SAP HR, to do posting.

regards
