Can't create (house) bank account in NWBC

Hi all,

I'm working on SAP S/4HANA ON-PREMISE 1511.

I have a problem in creating house bank account.

In particular, I have performed the following actions:

1) Customizing at following path: Financial Supply Chain Management -> Cash and Liquidity Management -> Bank Account management -> Basic Settings. I define “Number Ranges for Bank Account Technical IDs” and “Number Ranges for Change Requests”.

2) I access tcode NWBC with role SAP_SFIN_CASH_MANAGER. I create a New House Bank through “Change House banks (FI12_HBANK)”

3) Then I go to "Manage bank account" menu to create a new bank account but when I push the button "NEW BANK ACCOUNT" no action is performed.

So I can't create the bank account to link to my house bank.

Any help is very appreciated!

Thanks in advance for helping.
