New Accounting type in OB52 S/4 HANA 1709

Hi All,

Can anyone please tell me how to create new accounting type in OB52. Already I have a standard accounting type like S, K, D, M, A my client wants additional accounting type. if it reflects any transaction codes? I have one question it is related to the FI functional side or technical side?

Thanks in advance
