Import Issue - Same Primary Contact for Multiple Accounts

Hi,

Our organization has different Accounts with same Primary Contacts.

Example:

1)  Account:  Company_a        ,      Primary Contact:  Mr. A

2)  Account: Company_b         ,      Primary Contact:  Mr. A

During the import, these accounts are failed.  Error appears as:  "A duplicate lookup reference was found."

Currently, the duplicate detection is only for 'Duplicate Account Name'; which is not the case in above example.  Actually, this issue appears even when duplicate detection settings are disabled.

Please advise.  Thanks in advance.

Saima
