: Constrained Supply Plan Not Using Alternate Resource Despite Configuration in Routing&Plan Option

Summary:

I am working with Constrained Supply Planning in Oracle Fusion and facing an issue where the system does not appear to consider alternate resources, even after the production capacity of the primary resource is fully utilized.

Here are the steps I have followed:

• I have used the FBDI template to upload routing data and have correctly defined alternate resources in the routing.
• In the Supply Plan options, I have selected the checkbox to "Use alternate resources" .
  The alternate resources are defined with the appropriate usage percentages and effective dates.

However, during the plan run, the system continues to schedule work only on the primary resource and does not shift any load to the alternate resource, even when the primary resource is over capacity.
