Replacements Only

If a rejected tax filing contains the error code AIREX, AIRBR, AIRTN, or BIRTH, use this field to specify the type of replacement to be sent.

Transmission means that the entire transmission was rejected, which requires you to replace the entire transmission.

Submission means that one, or more, but not all, of the submissions in a transmission were rejected, which requires you to replace only the individual submissions that were rejected.
