If the ASN encountered an error during transmission, it will have a red icon indicating the error, and you can Edit the ASN using the pencil icon.
However, if it transmitted successfully, but with mistakes, I recommend reaching out to the receiving party to advise them of the invalid ASN, and resubmitting another. You should be able to create another ASN the same way you created the first one. If you run into issues re-creating the ASN, please contact our Support team using one of the below channels:
