Supplier Capacity constraint is not suggesting the alternate Supplier.
We have uploaded Supplier Capacity for 2 Suppliers and created Sourcing Rule with both the Suppliers as Rank 1&2.
Now, even when the demand is more than Rank 1 Supplier's capacity, the generated planned order is still showing all the demand quantity for Rank 1 Supplier only. The Supplier Capacity constraints have been enabled in the Plan options.
Also, there is no exception generated for this overload. How does the Supplier Capacity functionality work?
