Calculated Order Attributes

Constraint-based supply planning includes several calculated order and resource requirement attributes to help you diagnose issues in your plan. Some attributes are based on milestones on an order that are calculated as part of a plan run, such as Earliest Start Date.

Other attributes are explanatory order attributes, such as Shared Supply.

Milestones

These attributes are based on milestones.

Diagnostic Attribute	Applies to	Description
Need by Date	Supply and resource requirement	The date when the supply or resource requirement must complete to satisfy demand on time.
Earliest Start Date	Supply and resource requirement	The earliest possible date that a supply or resource activity can start, based on the nominal lead times of all pegged upstream supplies and resource activities.
Consumption Start Date	Supply and resource requirement	The date when a downstream supply or resource activity starts consuming the output of the supply or resource activity. If the supply or resource activity has multiple consumers, the earliest consumer is used to calculate this date.
Material Available Date	Supply and resource requirement	The date when the upstream supply or resource activity that feeds the supply or resource activity is planned to complete. If the supply or resource activity has multiple upstream supplies or resource activities feeding it, the latest producer is used to calculate this date.
Latest Start Date	Supply	The latest possible date that a supply can start so that it can complete by its need-by date.

Explanatory Order Attributes

These attributes are based on explanatory order attributes.

Diagnostic Attribute	Applies to	Description
Contributes to Overload	Supply	This attribute value is Yes if one of these conditions occurs: The supply is in a time bucket where it overloads supplier capacity. One of the resource requirements of this supply is in a time bucket where the resource capacity is overloaded.
Contributes to Overload	Resource requirement	This attribute value is Yes if the resource requirement is in a time bucket that overloads resource capacity.
Contributes to Demand Lateness	Supply and resource requirement	The attribute value is Yes if the Need-by Date minus the Earliest Start Date of the supply or resource requirement is less than the nominal lead time of the supply or resource requirement.
Shared Supply	Supply	The attribute value is Yes if the supply is consumed by multiple demands.
Uses Order Modifier	Supply	The value is Yes if the supply quantity has been determined by the use of an item level order modifier such as Fixed Order Quantity.
Pegged to Firm	Supply	The value is Yes if the supply is pegged to a downstream firm supply.
