 This module takes the potential quantities available for Products into account in
 the quantity available to promise, where the "Potential quantity" is the
 quantity that can be manufactured with the components immediately at hand.
+By configuration, the "Potential quantity" can be computed based on other product field.
+For example, "Potential quantity" can be the quantity that can be manufactured
+with the components available to promise.
