Question

I have a lot of orders and a limited fleet, so not all orders can be allocated. How can I tell OptiFlow that certain orders have to be planned in this planning but other orders are less urgent?

Answer
 

The orders that need to be planned can be made mandatory. Orders that do not have to be planned in this planning can be made optional (not mandatory). Orders that are not mandatory need to have a penalty cost. This represents the cost of not allocating this order in the planning.
