Dear Beatriz,
Let's assume that you have following demand situation at all locations.
DC1- 100
DC2- 100
WH- 100
Now if you execute the deployment heuristics we have the following situation
Reserved Quantity at WH- 100
Confirmed Distribution Demand DC1- 50
Confirmed Distribution Demand DC2- 50
Let me know if my understanding is correct. Please could you explain what is your expectation?
