Filed your CSN on the ICEGATE portal? Record it here and file its amendment (SCA) here

In this film

• Record a filing made elsewhere → I have an amendment to file
• The amendment (its file name starts A_) — it names the CSN it changes
• The filing that was accepted, and the ACK that granted the CSN — checked against the amendment and each other; a file that does not belong is refused, and says why
• What gets recorded: nothing is sent to customs — the accepted filing is put on record so the CSN your amendment references is one SCMTR can see
• Your amendment's changes, carried into the draft — and shown again in Changes before you sign
