hi Archana Kumari  thanks for reply.
I think my problem is different from the link that you have post.
my problem is
1.sales order 000001
    10. item 001 -> no discount
    20. Item 002 -> no discount.
1.sales order 000002
    10. item 001 -> has discount
    20. Item 002 -> has no discount
the rounding should be happen in sales order 000002 and will not happen in sales order 000001.
in which routine should i define code for activate the rounding.
please help me.
