MF60 pull list

Dear Experts,

What is the difference between the first 2 tabs of MF60 and 3rd tab?

I mean what is the difference between Planned orders and Production/Process orders with Planned/production/Process Orders tab?

If I put a material number in the first tab for which I am creating production orders from planned orders, I am not getting any proposals. But for the same material I am getting proposals in 2nd and 3rd tabs. Why is that? As I have open planned orders for the materials.

Also tell me does MF60 only consider Run schedule and not stock orders?

Does my planned orders have to be farmed to be picked under MF60?
