Import Error for Account Sales Data

Dear All,

I am very new to Oracle CRM on demand. I need to create new  Segment for full year and import Full year data in bulk. Can you give some pointers how to create a new segment and perform import activity.

In my source file below are the field name.

External Unique ID

Account

Country

Owner

Segment Name

Year

Quantity

Asset Type (Blank)

Vehicle Country (Blank)

Vehicle Year (Blank)

When I ran the import using import utility, the following errors are seen.

• No matching record is found for import field 'Full Year' with value 'Full Year'. The Oracle CRM On Demand field 'Segment Name' was not updated, but other field values were imported for this record.
