We found this out the hard way too. Our workaround: we added another bank account type to the UDC list (forget the exact UDC off hand). So, typically when you set up a vendor's bank account, you use bank type "V"... we added code "I" for Intermediary bank. Now, when we have a vendor that has an intermediary bank to use, we'll set up their local bank's info in the "V" type and the intermediary bank's info under the "I"...all under the same vendor, just different bank account types . This allows us to map to the intermediary account record for our banking interface extract
