Combinations for Setting Cardinality
The following table describes several combinations for setting cardinality. The table shows what the user will see in the initial solution and what actions that the user can take. In the table, N is the quantity of the default product in the initial solution. In all the cases where the Min Card is greater than 0, the user can substitute other products for the default product.
Min Card | Default Card | Max Card | Application Adds Default Product? | User Pick Reqd? | Initial Solution | User Actions Allowed |
---|---|---|---|---|---|---|
=0 |
= Min Card |
>Default Card |
