Preconditions

Decision tables contain a Preconditions section that lets you:

Set variables that can be used in the decision table. (This is explained in the Definitions part of a rule.)
Set a condition that is applied to an entire decision table. If the precondition is not satisfied, none of the rules in the decision table can be evaluated.

For example, you could apply the following precondition to a decision table:

 definitions
     set 'wealthy customer' to a customer
         where the average monthly balance of this customer is more than $1 000 000;
 if
     the state of residence of wealthy customer is NY

Applying this precondition to a decision table would limit the scope of the decision table rules to only those customers with an average monthly balance of $1 000 000 and living in New York. It would also allow you to create condition and action definitions using the variable wealthy customer.

Note

Preconditions cannot be edited in Rule Team Server or in Rule Solutions for Office. They can only be displayed.

See section Defining Preconditions for information on how to set preconditions in a decision table.
