Quotation confirmation

Hi Forum,

I have a simple scenario, wherein I send a simple quotation to the customer and customer in turn confirms the same so that i can create the Sales order.

Is ther any arrangement in SD that quotation can get confirmed through customer. A simple check will also work where customer gives the confirmation on phone and quotation is checked (as confirmed).

without confirming the quotation the Sales order should not be created.

Is ther any such provision in SAP.

Please give me your valuable suggestion.

Thanks and regards,

Ashish.
