Symptoms

Customer is implementing ASCP in release 11.5.10.2.
Customer uses unconstrained plan with the following plan structure :

A component with 2 possibles sources is defined and planned at MRP level.
Supplier A has 100 % allocation at rank 1, Supplier B has 100 % allocation at rank 2.
Supplier capacities are defined in the ASL.
Profile option "MSC: Enable Enhanced Sourcing" is set to "Yes".
When Supplier A capacity is overloaded, the ASCP Mfg plan gives an exception, but no planned order is created on Supplier B.

This test case we ran shows that Standard MRP will suggest orders from the Rank 2 supplied and Unconstrained ASCP plan should provide the same functionality.

ASCP Users guide states
Part No. B10144-10 July 2006)

Page 5-46 (about Decision Rules tabbed region) :
"For buy items in unconstrained plans and constrained plans in which this tabbed region is not available, you can duplicate the functionality of this region’s Use Alternate Sources parameter; set profile option MSC: Enable Enhanced Sourcing to Yes. You cannot duplicate this functionality for transfers from other organizations."

Page A-19 (about "MSC: Enable Enhanced Sourcing" profile option) :
Enables enhanced sourcing logic that considers historical allocations and allows the splitting of planned orders to achieve target sourcing percentages. Rank 2 buy sources are considered if supplier capacity is exhausted for rank 1 sources.
This profile option duplicates the functionality of the decision rule Use Alternate Sources parameter for buy items but not for transfers from other organizations. When the decision rules are enabled, the planning engine does not consider this profile option.

Page 9-45 (about Supplier capacity overloaded exception message) :
Unconstrained: Since unconstrained plans assume infinite capacity, the planning engine may issue many instances of this exception. If profile option MSC: Enable Enhanced Sourcing is Yes, unconstrained plans first exhaust supplier capacity from rank 1 suppliers and then use supplier capacity from rank 2 suppliers.

Page 9-78 (about Order sourced from alternate supplier exception message) :
In an unconstrained plan where profile option MSC: Enable Enhanced Sourcing is Yes, plans orders using supply capacity from rank 2 suppliers.



STEPS
Create item and demand
Create ASL for with supplier capacity
Run Standard MRP and then ASCP plans with same demand/supply data and observe results.
