Inconsistent Price, Quantity and Amount

We are trying to import invoices matched to PO where unit price is 6.102940 and Qty is 30.00.

The Amount inclusive of 13% tax is 206.89.

However Payables Import is erroring out with message Inconsistent Price, Quantity and Amount.

We think its because when import calculates the Line Amount 6.102940 x 30 = 183.08820 it is more than 2 decimal place accuracy.

How can we import such an invoice.

Thanks
