New t-code (FI12_HBANK) to maintain House bank in Simple Finance

Hi All experts,

When use the new t-code FI12_HBANK to maintain house bank in simple finance, I am not able to maintain the table T012K (bank account number, GL code etc).

I did a simple check, the old t-code FI12 is maintaining a cluster view VC_T012, but the new t-code is just updating the view V_T012 ONLY.

Is there a new way to maintain or it's a bug?

Regards,

Alex
