The purpose of keeping a minimum stock level is to enable the stock controller to avoid running out stock.

Stock levels must never drop below this Minimum Stock Level. 

This number is 0 (zero) only if backorders are not permitted.

It is determined by calculating the estimated amount of time from the beginning of production, through the time of transit, to the point at which the product is either "on the shelf" or in the hands of the customer who ordered it. 

Roadmap:

1. M Stock > M1 Stock setup > SM1 Stock levels per warehouse > Correct Category and Correct Warehouse > B Load Data.
