How to create text rules

A decision table rule is the collection of rule expressions in tabular format. The rule expressions are sequentially executed, and the matching rows are returned.

A text rule is a decision logic in a simple if-then-else format. A text rule evaluates a single rule expression and returns the result that matches the condition.

In this tutorial, we will create the decision logic required to assign equipment for the new hire, both as a text rule as well as a decision table.

Step 1: Create decision table rules

Navigate to the Rules > Local Rules tab, then choose +.
In the New Rule prompt, provide the following details:

Name Type

DetermineEquipmentRules Decision Table

Then choose Create.
In the New Rule page, provide the following details and then choose Settings icon.

Label Description

DetermineEquipmentRules Rule to determine equipment for the new hire based on the country and job title of the new hire.

The decision table settings window opens.
In the decision table settings window, select the Hit Policy as First Match. With Hit Policy as First Match, the decision table returns the first row that matches the condition.

In this tutorial, we are using the First Match hit policy. If you select All Match hit policy, all the rows of the decision table that matches the condition are returned. In this case, the result data object EquipmentInfo should be of type Table to hold all the row values.
Press CTRL + SPACE to load the autosuggestion list, and then choose Employee under Vocabulary section.
Choose the attribute Country or Region of Company from the Vocabulary section and then in the Label field enter Country or Region.
From the Fixed Operator dropdown list, select None.
Similarly, create the following condition expressions:

Condition Expressions Label Fixed Operator

Employee.company Company None

Employee.jobTitle Job Title None

Employee.isFullTimeEmployee Full time/Part time None

The label is displayed in the decision table column header.

Choose EquipmentInfo as the Result data object from the dropdown list and then choose Apply.

A decision table gets created with the condition columns and result columns.
In the Country or Region column, press CTRL + SPACE. Under Comparison Operators, select is equal.
Under Fixed Value section, select the value help icon to select the value.

Select USA from the value help.
In the Company column provide the following value using the autosuggestion list:

='ACE_USA'

Name	Type
`DetermineEquipmentRules`	`Decision Table`

Label	Description
`DetermineEquipmentRules`	`Rule to determine equipment for the new hire based on the country and job title of the new hire.`

Condition Expressions	Label	Fixed Operator
`Employee.company`	`Company`	`None`
`Employee.jobTitle`	`Job Title`	`None`
`Employee.isFullTimeEmployee`	`Full time/Part time`	`None`

In the subsequent cells, provide the following values:

Job Title	Full Time/Part Time	Product ID	Equipment Type	Price	Product Description	Currency
*`MATCHES '.'`**	`= true OR Employee.IsFullTimeEmployee = false`	`'A106743'`	`'Audio and Video'`	`35.96`	`'Lovely Sound 5.1'`	`EUR`

Select the first row, then choose Add Row > Insert After.

Enter the following values in the condition and result columns of the new row:

Country or Region	Company	Job Title	Full Time/Part Time	Product ID	Equipment Type	Price	Product Description	Currency
`= 'USA'`	*`MATCHES '.'`**	*`MATCHES '.'`**	`= true OR Employee.IsFullTimeEmployee = false`	`'C106875'`	`'Notebook'`	`956.00`	`'Notebook Basic 15'`	`'EUR'`
