If you run MR-f and dont get a long list of stuff then you dont need to make anymore more stuff.
Once you get the min levels calculated you will never run out of the stuff you need to stock.
I got all my items into a spread sheet and had it calculate the stock levels based upon how many we make in a year number of turns I wanted and lead time.
I can e-mail you the spreadsheet if you want it
After I got all the numbers I needed I used wintask and a spare computer to do all the data entry for me so it was painless to update all 10000 items.
