Currency while maintaining pricing

HI all experts,

I have maintained currency for the customer in XD01. It is USA customer and I have maintained USD in currency field in sales tab of sales area data in XD.

But in VK11 when I enter the basic price of the material for this customer and press enter the system by default takes currency as INR. This should not happen because if I am maintaining prices for 50 materils I have to change the currency also 50 times.

Please help. Rewards guarenteed.

Regards,
