Upgrade from R/3 to S/4 - Payroll and Time advices

[lucien_mathieu]

Dear Gurus,

did you upgraded you R/3 payroll and time solution ?

Any advice how to do it smoothly ?

What about an existing integration between R/3 and SF to be upgrade to S/4 ?

Thanks in advance.

Kind Regards,

Lucien.

Upgrading R/3 Payroll and Time to S/4HANA requires careful planning. Ensure compatibility with HCM for S/4HANA on-prem or consider migrating to SAP SuccessFactors. You should test all payroll schemas, time evaluations, and reports before go-live. For existing R/3 to SF integrations, check middleware (e.g., SAP CPI) and update APIs accordingly. A phased approach with thorough testing ensures a smooth transition.
