A forecast reduction key that is defined on a daily basis to reduce a forecast to a daily level is messed up when non-working days are used as part of the calendar, such as a weekend. For example, I set to reduce 100% on day 1, 50% on day 2, 0% from then on. If I have forecast for M-F, then on Friday when I am planning for M/Tu, the reduction is applied to Sat/Sun and not M/Tu, thus rendering the reduction key useless for this scenario. (This is more problematic in short lead time, made to order scenarios.) The idea would be to have a flag similar to other areas of D365 where we can say that a reduction key is applied to calendar working days only.
