Scenario Overview

In this scenario we will demonstrate how to quickly and easily set up a Decision Table based around Credit Cards.

For this article it is assumed that you have at least basic familiarity with Decision Tables and/or have read the following articles:

• Everything you need to know about Decision Table Conditions
• How to set up your Actions!

We will use the following custom fields on the Contact entity to decide if a customer is entitled to a Platinum Credit card:

• Annual Income
• Total Assets of Applicant
• Credit Score

If a customer matches any of the scenarios below then they are entitled to a Platinum credit card.
As you can see there are 12 possible combinations each with 3 variables to check which means 36 data points to check.

The easiest and fastest way to achieve the desired functionality is with a North52 Decision Table.

N52 Formula Manager Solution

The Formula Manager solution works like this,

• A new North 52 Formula of type 'Save - Perform Action' is created on the Contact entity
• The Source Properties for this formula are 'Annual Income', 'Total Assets of Applicant' and 'Credit Score'
• Set the Event to be 'Create & Update'
• Switch the North52 formula to the Decision Table editor (Commands > Toggle Editor)
• Add 2 additional Condition Columns and set the 3 Columns to check against the Annual Income, Total Assets and Credit Score
• Set the Action Column to update the Credit Card field.

• Finally we add the condition values to the to Decision Table editor and save

Note: The ((150000, 200000)) syntax is inclusive of 150000 and 200000.

Testing the Decision Table

We open a Contact record and set the following fields and values

• Annual Income to €120,000
• Total Assets of Application to €440,000
• Credit Score to 174

When we click Save the Decision Table updates the Credit Card Type accordingly to Platinum
