However, I need to ger S2 (Saftey Stock) in weeks. Meaning I want to keep 2 weeks of inventory on hand. I assume I can't just multiply by 2, it doesn't seem right.
Someone please assist. The forulas and explaination of columns is listed in the comment boxes.
Basically I want to keep 2 weeks of stock on hand and get only one delievery per week.

I think I went seriously wrong somewhere with my forula for mi and max levels.

Thanks
