The 1099 process looks at the payee id on the voucher. Thus, the recipient of the check is the one associated with the 1099.
When you print out the 1099 form, the name, address and of course the Tax-id is printed on the form. When you pay a consultant who does not have a Profile in FIMS, please note that you have not included the Tax-id anywhere in FIMS. This should help you remember that you haven't properly set up the Grantee or Admin Voucher for 1099 printing. You should always create a profile record for selecting for the payee id in the voucher if the recipient should receive a 1099. You should not leave the payee id as the grantee id and just edit the name and address on the voucher.
