How to create text rules

A decision table rule is the collection of rule expressions in tabular format and sequentially executes each rule in the table.

A text rule is a decision logic in simple if-then format. The If condition of the text rule is evaluated by the system once the rule is triggered. Based on the result of the condition, the rule performs a set of operations.

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

Field Name	Value
Name	`DetermineEquipmentRules`
Type	`Decision Table`

Then choose Create.

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

Field Name	Value
Label	`DetermineEquipmentRules`
Description	`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.
Press CTRL + SPACE to load the autosuggestion list, and then choose Employee under Vocabulary section.
Choose the attribute countryofCompany from the Vocabulary section.

The label Country or Region of Company of the attribute countryofCompany, is displayed in the list.
From the Fixed Operator dropdown list, select None.

Similarly, create the following condition expressions:

Condition Expressions	Fixed Operator
`Employee.company`	`None`
`Employee.jobTitle`	`None`
`Employee.isFullTimeEmployee`	`None`

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 as shown:

In the Employee.countryofCompany 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 Employee.company column provide the following value using the autosuggestion list:

='ACE_USA'

In the subsequent cells, provide the following values:

Field Name	Value
`Employee.jobTitle`	*`MATCHES '.'`**
`Employee.isFullTimeEmployee`	`= true OR Employee.isFullTimeEmployee = false`
`Currency`	`EUR`
`ProductID`	`106743`
`Equipment Type`	`Audio and Video`
`Equipment Price`	`35.96`
`Product Desc`	`Lovely Sound 5.1`

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

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

Field Name	Value
`Employee.countryofCompany`	`= 'USA'`
`Employee.company`	*`MATCHES '.'`**
`Employee.jobTitle`	*`MATCHES '.'`**
`Employee.isFullTimeEmployee`	`= true OR Employee.isFullTimeEmployee = false`
`Currency`	`EUR`
`ProductID`	`106875`
`Equipment Type`	`Notebook`
`Equipment Price`	`956.00`
