When transmitting from Supply Chain to Acelynk and there's no matching part# in Acelynk

Recently, I've add several entries we've transmitted and even though there's no matching part# in Acelynk the entry transmitted from Magaya to Acelynk and it randomly defaulted to an HTS# that was not correct. Since there's no error message, we weren't aware of the issues until we filed the entry and reviewed the 7501 and found the duty to be incorrect. See attached email chain with Acelynk customer support regarding 1 specific instance. It would be better that if there's no matching part# in Acelynk to have an error msg pop up and halt the transmission so that we know to set up the part# in Acelynk before trying to transmit the entry again.
