While configuring the currency settings for company code, what are the two standard currency types that must be used? I was going through multiple documentation and posts and am a bit confused. Company code currency is definitely one of them, I am confused between document currency and controlling area currency as the second mandatory currency type to be configured. As I understand, company code and controlling area currency are reserved, but is it really mandatory to assign controlling area currency during the currency configuration set up? This is for S/4HANA 1809. Appreciate all the help.
