Find Columns and check the option Highlighted Notifications.
Use the filter field an choose the option ContainginNotificationTypeID (if you do not know the type of message).
Then choose ContainingNotificationTypeID, which will open a popup where you can choose the filtered categories of Sales Order Items, based on your access level.
Choose the category you suspect the Item will be in and click the Select button.
