The positive outcome will be the 277 response. Negative outcomes will result in negative TA1 and/or 999 transactions.

Re-transmission Procedure

If the test file generates a negative TA1 or negative 999 acknowledgments, then the submission is unsuccessful and the file is rejected. The trading partner needs to resolve all the errors that are reported on the negative TA1 or negative 999 and resubmit the file for test. Trading partners will continue to test in the testing environment until they receive a positive TA1 and positive 999. Receipt of a positive TA1 and 999 transaction is considered successful testing. Trading partners are allowed to submit production files once they successfully completed testing.
