I am using Magento 1.8.0.0 version with Paypal Website Payments Pro Payflow Edition (Includes Express Checkout) Payment Methods for my website.

I have used shopping cart price rule to give some discounts to customers. But whenever discount is applied , the payment methods will not recognized orders. It seems the below error message.

PayPal gateway rejected the request. Field format error: 10431-Item amount is invalid

But the payment gateway works fine without shopping cart price rules.

How do I fix this issue?

Any help much appreciation!.

This seems to be a price rounding issue. The Magento might has calculated the price as more than two digits after period while Paypal considers just two. Example Magento resulted the price as $24.449 while Paypal just considers it $24.44.
