Not Found means that the Treasury does not have in its possession records voucher, this may be due to the person issuing it not reported proof, this may be due to the speed of server PAC hired yet this does not mean that the voucher is not valid, need to check AGAIN usually it takes no more than 96 hours to be reported.
