Graphical Mapping Errors- File to Idoc- Creating Orders05

Hi Experts/Gurus

I have to create a new Orders05 Idoc for every change in BILLING_DOC. I have attached the test file. So for e.g- if i have to the Billing NO is same for 2 items- as in my case ("91500963")- i want to create only 1 Doc for them

I tried all the different ways but still it would create  3 Idoc's for the test file, where I want only 1 Idoc

All inputs would be appreciated.
