Defining preconditions

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

About this task

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

  • Variables that are available throughout the decision tree

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

Procedure

To define a precondition:

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

    The Content Assist box opens. You define variables and conditions in the Preconditions section in the same way as 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 tree.

    The variables you defined are now available for creating condition nodes and branches in the decision tree, which means the decision tree cannot be evaluated before the conditions defined in the precondition are satisfied.
