Creating a Decision Table and Inserting a Rule

In this step, you add a rule to your process. You define the rules to be applied in a decision table (.rule). For this example, you create a decision table that determines the following:

• All invoices with an invoice value below 1000 will be automatically confirmed.

• All invoices with an invoice value greater than or equal to 1000 will be checked manually.
