Electronic Batch Payment and Bank Account Assignment Details

Hello,

We are having an issue with Electronic Payments and it Account Assignment, as you know when you are adding the banking details you have the option to assign it to the Supplir,Site or Address, ect.

If I assign it to the supplier, it works perfectly when doing quick and batch payments, but if I assign it to the site (which is what I will need) it works perfectly when doing a quick payment, but when I do a batch payment all the information regarding the bank account, check digits and account type comes as 0000.

Please help, I dont know what else to do.
