EFT IAT Format (R04572T3)

Is there a document anywhere that details how the ODFI and RDFI are to be set up?  I've done what the implementation guide recommends (below), but when I run the output file, it's still pulling the bank transit information from the bank account instead of the ODFI.  Same with RDFI for the supplier. 

To support IAT format, enter the bank information of a foreign Originating Depository Financial Institution (ODFI) using the Foreign ODFI Row menu option on the Work with G/L Bank Accounts form. If you select the Foreign ODFI option, then the system creates a new record in the Bank Transit Master table(F0030) with a value of O in the Bank Type field.
