schedule line logic

Hi Experts,

I would like to know a small logic on how to derive deliver qty based on schedule line. Am an ABAP developer. In one of my requirement i need to get the deliver quantity based on sales document , item and schedule line.

i have an deliver document : 12345 , Item : 20 ,

schedule line : order qty, rounded qty, confirmed qty, deliver qty

15 , 15 , 8 , 8

0 , 0 , 7 , 7

When i check in LIPS table am getting the deliver qty like 8 , 2 , 5 . The deliver qty has been splited. In my report i need to show for which schedule line the are delivered. As i have only two schedule line in VBEP . when i execute am getting only two deliver qty like 8 , 2 . In my report i need to show also the 5.

So i would like to know where i can find for which schedule line the are getting spited. If you can give me the details where i can find this information it will be helpful for me to build the logic. If you have any table name where i can find this information also it will be more useful for me.

Kindly let me know if you need any more information.

Thx in Advance.
