ABAP Query : code to change the display

Hi all,

I have created an Abap Query and generated it. I see the output now as follows:

Bill.doc Item Net value Total amt

900000 10 100 600

900000 20 200 600

900000 30 300 600

900001 10 250 250

900002 10 300 500

900002 20 200 500

Now I want the total amt to be displayed only once for each billing document only for the first item and for the other line items it should be blank as shown below.

Bill.doc Item Net value Total amt

900000 10 100 600

900000 20 200

900000 30 300

900001 10 250 250

900002 10 300 500

900002 20 200

Can someone please explain me where and how I should write the code to get this working?

Thanks,

N
