Batch management

Dear Gurus..

Our client wishes to have batch management for the Goods Receipts(for raw materials) and for Finished Goods after Production (Both External)...

Pls advice me

1. How to activate the Batch Management process correctly just (in the material master purchasing view)

2. How to assign Number Ranges in Alpha-Numeric for a particular Movement Type say 101 etc

3. What other settings necessary for correct batch management to happen

Thanks in advance
