Business Unit default payment bank

Hello,

  We created a new Business Unit(BU)PeopleSoft 9.2 PUM 23. We originally have 2 BU.  We created our 3rd BU and I need help on setting up the default bank.  When I create a voucher on the regular entry page, the 3rd BU is still inheriting the 1st BU's bank. Do you know where I can set this up? Please attached screen shot where I set the BU and a screen shot of the regular entry screen.

Thank you,

Dante
