The following IMOS forms include an Alerts field, which is a free-form text field that can be used to capture issues:
If an Alert is entered for a counterparty, Vessel, or Port, that field is highlighted in light red on the Cargo/VC In COA, IMOS - Cargo/IMOS - VC In, TC In/Out (Address Alerts only), IMOS - Voyage Estimate, IMOS - Voyage Fixture, and IMOS - Voyage Manager.
When you hold your mouse pointer over the field, a tooltip shows the text of the Alert.
An Alerts column can be selected to appear in the Address Book, Vessel List, and Port List.
