OO Call Method - How to Efficiently Export a Large Internal Table

I am trying to create methods and to keep things as modularized as possible. I want to call a method from my program to read line items from my calling program's internal table called itab_BSEG. I can use a binary search and field symbols in the method for efficiency.

However, in order to do this I would need to pass the large itab_BSEG to the method, so the method would return a small table of line items, itab_line_items, for my Order Number.

Is there a way to efficiently pass the large internal table of itab_BSEG to the method for processing? Or, in this case am I better off just processing the data from where itab_BSEG lives in the calling program?

I've heard of shared memory, are there any other ways to do this with pointers and addresses so the large internal table can be passed efficiently with little crunch on the system?

I am on 4.6C

Thank-You
