How to create free goods

Dear gurus

regarding the Free Goods I have an issue in My Company..

we have Material Groups and under each group there are many SKUs in different pack sizes and different shades.

if we want to give Free Goods on Material Group Basis for example

For Material Group A there are say SKU A2222,

A2223 and many more

now if we want to give free goods from another material group like if anybody purchases any item from Material Group A then a 2% free goods of materila group B can be given in the order level.

this would be a great help for me if anybody can comment

thank you
