Deleting lines from internal table whose sum is 0

Dear Gurus,

Hope you all are fine. I made a report and i need to do one thing in it. I need to delete those lines from internal table who have same document number, item number and whoso sum is equal to 0. Look at the screen shot. There are two lines, highlighted in orange, and i need to delete these lines because they belong to same document number, item number and their sum is 0.

can anybody tell me how can i delete these line items. Thanks in advance.

Regards
