Distribution of line amount

 Hi All,

   Can we distribute line amount?

If yes hoe do we distribute? On what basis we distibue?

Example :

I have a transaction  number is  : ABC

This ABC is having 2 lines A1, B1

A1 line amount is 500

can I distribute this 500 like 250

                                             100

                                              150

If we distribute like this where will it store(I mean table name)

Thanks,

Radhi
