sales order net value and invoice net value differ
i placed sale order 03/08/2009 the net value of the order is 30000 USD, the same day i have done some price modification (manually i entered the header condition with value of 50 USD) after entering the header condition sales order net values is showing 50 USD. then delivered and invoiced. in the invoice net value is showing 30000 USD. my requirement is the invoice also has to show the 50 USD only. why it is not showing the sales order net value? is there any setting need to be done regarding this problem?
Thanks in advance
