Is it possible in S/4 HANA on-premise set-up a 2-system landscape? Advantages and disadvantages?

[VictorHugout]

My doubt arises because theoretically, managing two systems could simplify operations. In the clients I have worked with, there has always been a 3-system landscape, and I wonder why it remains the default configuration currently.

Thank you very much

Hi,

thats right 3 is standard.

But for smaller companies or for start of project 2 system might be also sufficent.

Later you could always add a system for 3 system landscape, or 4 (Sandbox),.....

Kind regards

Robert
