Once you’ve tackled challenge one, getting your Suite on HANA system registered properly into SAP Solution Manager, the next challenge arises, getting the right packages selected through the maintenance optimizer (or landscape planner) to implement SFIN 2.0.
If you’ve got SFIN 1.0 then SFIN 2.0 is visible under add-ons. Without SFIN 1.0 (so just ERP 6), neither SFIN 1.0 nor SFIN 2.0 was visible for me under add-ons. Instead it is visible through support package stack application instead (in a nutshell, screenshots below).
I didn't really see any information source mentioning this and this can be confusing for SAP Basis administrators so I decided to post this small blog.
Without SFIN 1.0, select Support Package Stacks
Click Continue
Select stack level which is applicable for SFIN 2.0
Keep an eye on SAP note 2117481 - Release Information Note: SAP Simple Finance, on-premise edition 1503 for this purpose
Select Applications for FIN 700
Click Continue
Click Continue
Select SAP Simple Finance 2.0 which is named SAP SFINANCIALS 1503 (released on 15/03) and click Apply
There are also related (updated) components for SAP Fiori and SAP Smart Business for SFIN 2.0 which you should include:
Note that moving your Suite on HANA system to S/4HANA SFIN 2.0 is not just a technical process, you need functional preparation before even doing any technical steps (except for SAP note implementation). Please read through all available documentation and SAP notes carefully before jumping into SUM.
