The Integrator searches for the first available Cancel Action. When found, irrespective of what data exists in each section, the underlying web service will perform a cancel operation at that level.
To cancel an entire purchase order and all its open lines and schedules simply enter Cancel in the Header Upload Action column.
To cancel a purchase order line and all its open schedules enter Cancel in the Line Upload Action column.
To cancel a purchase order schedule, enter Cancel in the Schedule Upload Action column. If the Line Upload Action column in this scenario also contains Cancel, this will be ignored as the Schedule Upload Action takes precedence and the line will not be cancelled unless the schedule being cancelled is the last open schedule on the purchase order line.
