Critical Path
The critical path of a demand (such as a customer order line item) consists of all the items in the bill of material that directly affect the completion time for the demand. Any delay in these critical-path items will cause the demand to be late. The critical path is calculated twice during APS planning: once using the pull pass and once using the push pass (if the demand is late). Both critical paths are viewable in the Demand Detail form, but the pull critical path is used by default.
