In short: it maps finance and logistics as the twin core of an S/4 system, using the fictional company In-House Secure to show real configuration dependencies, taking into account the guiding principles of the Fast Implementation Track. It matters because most project confusion starts from missing the sequence and meaning behind setup decisions. Use it when you need to understand why, what, and when each configuration choice occurs, and avoid it when you just want a transaction code or step-by-step guide.

The FIT 4 SAP Exploratory Call
FIT 4 SAP is a public reference that shows how the moving parts of S/4HANA link together.
It is not a how-to guide.
It answers three practical questions:
Each page follows the logic you would face if you were setting up S/4HANA yourself: you normally define a Company Code before a Controlling Area, before a Plant.
This cause-and-effect chain repeats across all processes.
Understanding it saves weeks of rework and political debate later.
If you work with SAP S/4HANA — functional consultant, solution architect, project manager, or even a curious analyst — this site is for you.
