The determination of the ATP time fence does not support working days. When the ATP time fences are typically around 2 to 4 working days, there is no correct way of entering an ATP time fence. It makes a big difference if there is a weekend in between.

Proposed solution is to add in the default order settings (initialized from the accounts receivable parameters, tab Shipments) a checkmark Working days.

Working days should depend on 7 new "ATP working day" parameters Mo, Tu, We, Th, Fr, Sa, Su.

In the ATP calculation (class SalesATPCalulcation), if the ATP time fence is in working days, the non-working days must be added to the ATP time fence (salesATPSettingsMap.atpTimeFence).
