Defining preconditions

You define preconditions to create variable definitions that are available throughout the decision table and conditions that must be satisfied before the decision table is run.

About this task

You can define preconditions for a decision table. Preconditions can contain the following definitions:

  • Variables that are available throughout the decision table

  • Conditions that must be satisfied before the decision table is run

Procedure

To define a precondition:

  1. In the decision table editor, click the General tab.
  2. In the Preconditions section, press Ctrl+Spacebar.

    The rule completion menu opens. You define variables and conditions in the Preconditions section in the same way that you would create variables and conditions for an action rule in the Intellirule editor. See Building rules by using the Intellirule editor for details.

  3. Save the decision table.

    The variables you defined are now available for creating condition definitions in the decision table, which means that the rows of the decision table cannot be evaluated before the conditions defined in the precondition are satisfied.
