You cannot use the reverseCalculateTargetDates plug-in with the other two plug-ins. The setProductCalendarTargetDates and updateProductCalendarDates plug-ins set the product or colorway target dates based on the season calendar, while the reverseCalculateTargetDates plug-in is using the reverse calculation logic. While the system does not display an error message when you use multiple plug-ins, the target dates might be confusing. Some dates might be based on one plug-in, while other dates might be based on another plug-in, depending on which plug-in is executed last.
