S/4HANA & core ERP

S/4HANA programs need more than an S/4HANA keyword.

Conversion, greenfield or selective data transition: the approach decides which functional, migration and technical experience the program needs, and when.

Questions worth asking before the shortlist.

Is this a conversion, greenfield or selective transition?

A conversion lead and a greenfield solution architect are different hires, even when both have S/4HANA on the CV.

Which simplification items hit your custom code?

Custom code remediation decides how much ABAP capacity the program needs, and when.

Who owns business partner conversion?

Customer / vendor integration is often the first conversion blocker. It sits between finance, logistics and data.

Who has run a cutover weekend?

Cutover and reconciliation need people who have been in the room at go-live, not only in the planning.
