SAP S4 Hana - Best Practices and another countries
We've installed SAP S4 Hana on premise edition with all the best practices activated in our demo environment.
Now we've two companies in the system created by the best practices for DE and US.
Our goal now is to create another company but with other country which we don't have best practices. What is the best approach for this? Do the customizing just like the old way or can we adapt the standard best practices for US or DE for this country?
Another question regarding future upgrades, if we change the standard configurations maded by the standard best practices could this changes be replaced by future upgrades?
