SAP HCM Timesheet || Timesheet data upload into SAP from 3rd party tool

Hello Experts,

I am having a requirement from my client to configure SAP in such a way that timesheet data will upload into SAP directly from 3rd party tool. My client is currently using 3rd party application for swipe in/out. Txt file is getting stored in Application Server. And then using another 3rd party application for time and payroll processing. Now we want to upload time data directly into SAP.

Could you please provide me how can I configured this process in SAP? What will the process? How time data will get reach into SAP? In infotypes(2001/2002/2011) or directly into CATS?

Steps if any?

It will be great help.

Thank you.
