Hello Jana,
as one-step procedure is a technical lifecycle procedure combining several steps within one downtime. For example combining database migration and installing additional software in one step.
For SAP S/4HANA, on-premise edition 1511 it is possible to combine the installation of the S4 software and the database migration in one step. For a customer on ECC6.0 (on any EHP) and SAP HANA, it is anyway just the intallation of the software for SAP S/4HANA, on-premise edition 1511.
Regarding sFIN / SAP Simple Finance 1503 I can not give you the detailed information source accordingly please have a look in the sFIN documentation: SAP Simple Finance, On-Premise Edition – SAP Help Portal Page
Regarding SAP S/4HANA, on-premise edition 1511:
- 1511 is released and the software is available on Service Marketplace
- Additional information regarding installation and configuration can be found here: SAP S/4HANA, on-premise edition – SAP Help Portal Page
