Exceptions in a Constrained Supply Plan

You can evaluate a plan and prioritize the manual changes to perform based on the exceptions generated from a plan. Oracle Supply Planning provides several exception messages for constraint-based supply planning.

You can drill down on an exception to obtain more detailed information about the exception. These are the four types of exceptions for a constrained supply plan.

• Demands at Risk Exceptions

• Late Supply Exceptions

• Overloaded Capacities Exceptions

• Usage of Alternates and Substitutes Exceptions

Demands at Risk Exceptions

This table shows the demands at risk exceptions for unconstrained and constrained supply plans.

Exception	Exception is generated for the following conditions:
Demand at Risk Due to Insufficient Lead Time	Suggested order date is less than plan start date. Reschedule days is less than 0 (Reschedule in Recommendations). Firm status is set to Not Firm. Note: All three conditions must be met before the planning process generates the exception.
Demand at Risk Due to a Resource Capacity Shortage	Resource availability is less than the resource requirements for the resource capacity measures of any resource used in making any supply that's end-pegged to the demand.
Demand at Risk Due to a Supplier Capacity Shortage	Supplier capacity availability is less than the supplier capacity required for the supplier capacity measures of any item that's end pegged to the demand.

Late Supply Exceptions

This table shows the late supply exceptions for unconstrained and constrained supply plans.

Exception	Exception is generated for the following conditions:
Late Supply Pegged to Forecast	Days late is greater than 0 for the Days Late demand order attribute. This condition means that the demand could be at risk due to the late supply.
Late Supply Pegged to Sales Order	Days late is greater than 0 for the Days Late demand order attribute. This condition means that the demand could be at risk due to the late supply.
Orders with Insufficient Lead Time	Suggested order date is less than plan start date. Reschedule days is less than 0 (Reschedule in Recommendations). Firm status is set to Not Firm. Note: All three conditions must be met before the planning process generates the exception
Orders To Be Canceled	The planning process detects a supply order that's not firm for which you don't need to satisfy demand or safety stock requirements. The planning process: Suggests that you cancel the supply order. Continues to plan lower item structure levels as if you accepted the suggestion.
Orders To Be Rescheduled In	The planning process detects a supply order that's not firm with an original due date that's later than the suggested due date. The planning process: Suggests that you reschedule the supply order to an earlier date. Continues to plan lower item structure levels as if you accepted the suggestion.
Orders To Be Rescheduled Out	The planning process detects a supply order that's not firm with an original due date that's earlier than the suggested due date. The planning process: Suggests that you reschedule the supply order to a later date. Continues to plan lower item structure levels as if you accepted the suggestion.

Overload Capacities Exceptions

This table shows the overload capacity exceptions for unconstrained and constrained supply plans.

Exception	Exception is generated for the following conditions:
Resource Overloaded	Resource utilization percentage is greater than 100.
Supplier Capacity Overloaded	Supplier capacity utilization percentage is greater than 100.

Use of Alternates and Substitutes Exceptions

This table shows the use of alternates and substitutes exceptions for only constrained supply plans.

Exception	Exception is generated for the following conditions:
Order Sourced from Alternate Facility	Alternate Facility Used attribute is set to True. The order is sourced from an alternate facility due to the material, resource, or lead time constraints.
Order Sourced from Alternate Supplier	Alternate Supplier Used attribute is set to True. The order is sourced from an alternate supplier (Rank 2 supplier and higher) due to the supplier capacity constraints.
Planned Order Uses Alternate Work Definition	Alternate Work Definition Used attribute is set to True. The planned order has used an alternate work definition due to the material, resource, or lead time constraints.
Planned Order Uses Alternate Resources	Alternate Resource Used attribute is set to True. The planned order has used an alternate resource due to the capacity constraints.
Planned Order Uses Substitute Component	Substitute Component Used attribute is set to True. The order has used a substitute component. The scenarios where this exception is generated are: The primary component lead time is long, which causes demand lateness (Lead Time Constraint). The supplier capacity of the primary component isn't sufficient, which causes lateness (Supplier Capacity Constant). The resource capacity for making the primary component isn't sufficient, which causes lateness (Resource Constraint). The Create Supply plan option is set to No for the primary component and there's enough on hand or capacity available on the substitute component.
