Sales tax on freight

Dear pandits,

I have two scenarios,

1. Calculation of sales tax on basic+ ED+ freight charges.

2. Calculation procedure as basic+ Freight + ED+ sales.

Need

There are companies who levy sales tax on freight as freight being part of material movement.

Also, there are manufacturing units imposing Ed on basic + Freight , being the freight charges part of material cost and the structure becomes basic+ freight + ED+ sales .

Please help will SAP support this schema and the methodology too

thanks
