How to capture the customer payment from the Sales order window.

 Hi,

I want to know is there any possibility to capture the Customer payment and the receipt details from the Sales Order window.

I have seen the Payment window from the Sales Order-->Actions-->Payments

From here i can capture the payment type as Cash.But the System won't allowed me to enter the Amount annd it was asking for the Receipt method only.

When i click on the View Receipts, no Receipts found message was displaying.

So please tell me is there any setup for the Customer payment and the receipt capture from the Sales Order window itself.

Thanks & Regards,
