Introduction

In a project, there are a few repetitive tasks that need to be done regularly or on some Business criteria. Business Rule 2.0 helps you perform such repetitive tasks so that you can save your time and focus on more important work. With Business Rule 2.0, you can automate certain things in your projects depending on specific criteria. 

Navigation

To configure a Business Rule 2.0, navigate to the project, hover over the top breadcrumb, expand the Configure menu, and select Business Rules 2.0.

Note: The menu is only accessible to the Project manager persona of that project.

Advantages of using Business Rules

• No coding or scripting is required.
• Reduce the manual work and fasten the day-to-day processes.
• It saves time for team members to focus on other important things.
• Creating Business Rules in Nimble is easy as you can visualize the flow of the rule which helps you understand the triggers, conditions, and actions, in a better way.

Prerequisite

Business Rules 2.0 can be created for Form 2.0 forms only. It lists only the forms in the card type section that are configured through Form 2.0. 

Main Components of Business Rule 2.0

A Business Rule 2.0 is made up of 3 important parts – 

• Triggers 
• Conditions and Conditions Group
• Actions

Triggers 

Triggers are the events that kick off a rule. If a certain trigger /event occurs, then the rule defined on it will be kicked off. They start the execution of your rules. Triggers will listen for events in the application, such as when a form is loaded or when a field value is changed. 

There are two types of triggers – 

• On Load – Business Rule 2.0 will be executed if the form is loaded/ reloaded. 
• On Field Change – Business Rule 2.0 will be executed if the value of the set field is changed. 

Note: The On Create and On Update triggers will be available soon. 

Conditions 

Conditions let you refine a rule. For example, if the defined condition is Priority = High for a form, then if the priority is set high in an instance the rule is executed on that form instance.

Conditions let you refine the scope of the event trigger for your business rule. They must be met for your rule to continue running. Conditions can be like when an attribute in a particular form has a defined value. For example, if priority is high, then “Mark Robinson” should be set as the card owner or the Class of Standard is Expedite, etc.

You can select single or multiple conditions for a Rule. For example, a Rule should be executed if the Priority is High and the Card Owner is Unassigned. The conditions can be applied to attributes.

To set a condition for a rule, you need to first select the card type and then the value for its attributes. So, if the selected card type has the value (set in the condition), then the condition will be fulfilled and the rule will be executed.

Business Rule 2.0 supports the following conditions as per the field type –

Field Type	Supported Conditions
Text	Is Is not Contains Does not contain
Number	Is equal to  Is not equal to Is greater than Is less than
Date and Time	Is Is not Is after Is before

Actions 

When the defined condition is met for a form instance then the set actions are executed. For example, if a Rule says, set Owner = Mark Robinson if the Priority is high then on setting the priority as High of that instance, the owner is set as Mark Robinson.

Actions are the doers of the rule. They let you automate your activities and make changes within forms. They allow you to perform many activities, such as editing the attributes of a card, sending mail, creating a new card, and so on. 

Business Rule 2.0 supports the following actions for all the field types – 

• Show Tabs 
• Hide Tabs
• Show Blocks
• Hide Blocks
• Show Field 
• Hide Field
• Set field as mandatory
• Set field as optional
• Enable Fields
• Disable Fields
• Set field value 

How to Create a Business Rule 2.0 

You can create a business rule 2.0 for the forms configured through Form Configuration 2.0 only. The product shipped form and the ones not configured through Business Rule 2.0 do not appear in the Rule 2.0 creation list. For example, let’s create a rule for the Purchase Order form so that if the customer address is out of California state, then the shipping value should be charged as 200 per order. 

To create a rule, perform the following steps – 

1. Navigate to the Business Rule 2.0 listing page.
2.  Click the ADD button on the top right corner.
3. To enter the name of the rule, click in the Rule Details box and enter the Name and Description of the rule.
   
   
4. Select the persona to which the rule should be applied like Team Member, Project Manager, or all, and click the NEXT button. By doing this when the rule is getting executed it will check for persona first. As shown in the below screen the Rule is applicable for the persona Consultant, Customer, and Executive. If any other persona logs in and triggers the same rule as defined in the Business Rule then it will not execute the Business Rule.
   
5. Click on the Select event trigger to call the rule box to select the trigger such as On load, or On field change. The rule will be triggered when the selected event occurs. For example, if the trigger is On field change, then the rule will be triggered on the change of the field value.
   
   
6. Select the card type and field on which you want the rule to apply and click the NEXT button.
   
   
7. Click on the Add icon to add the action or condition for the rule.
   
   
8. To specify the condition for the rule, click Condition and specify the field name, condition, and the value for the field name. On meeting this condition, the rule will be executed. You can also add multiple conditions by clicking the Add icon at the end of the condition or delete a condition by clicking the Delete icon. Click NEXT. To know the list of available conditions, read here.
   
   
9. Click the Add icon to define the action for the given condition.
