Function Module for complex selection of articles ?

Hi there,

I'm working on a transaction to display material information (MM), like in MM43 but with data of other tables. I am designing the whole thing using my own screens. Unlike MM43, the user must be able to select more than one article in the first screen.

Do you know any function module or class method to do a multiple selection or articles, as the one in MM13?

Something that I can call in my PAI and that returns the range of articles/ranges of articles included and excluded in the selection?

thanks
