Change in supplier site will result in loss of Remit-To Bank Account details on the invoice workbenc

Hello all,

When the site of the supplier in the site is changed, then the remit to bank account number of the new supplier site does not showup on the invoice workbench.

Setps to reproduce.

1. Create an invoice against a supplier with site1 which has remit to bank acc no as 12345678.

 Here the remit-tobank account number shows up as 'xxxx5678'

2. Save the invoice and then change the site on the invoice from site1 to site2( which has acc no as 87654321)

 Here the remit to bank account number is blank.

Is this a bug? Did this occured to any one?
