The cancel order day in vendor by site information should have been considered by the following business rules: 1. If 'Cancel Order Day' in vendor by site is not defined (null) or defined as '0', system will not automatically close or cancel the order. 2. For multiple OL order, the maximum value of cancel order day from all OL in the order will be considered. Null or '0' cancel order day will take first priority, means in case cancel order day of some OLs in the order has not been defined or defined as '0', system will not automatically close or cancel the order.
