When the scheduler runs, each orderpoint will check the forecast stock
for an infinite time. As example, if we plan a receipt of 10 products in
4 months and need to deliver 5 products next month, procurement will not
be launched since we have a forecasted quantity of 5.
In order to improve it, the orderpoint will compute the total lead days
from rules, suppliers/production delays, security days,...
Those lead days will be added to today in order to know at which date
the forecast stock should be checked and trigger the replenish document
for today in order to be delivered at the correct date.
