ServiceNow CPQ scripting language reference

View the operators, objects, and keywords that ServiceNow CPQ supports, together with information about type conversion, type checking, alternative scripts for unsupported operations, and accessing object properties.

ServiceNow CPQ uses a JavaScript-like language to dynamically change the value of fields and BOM data via rules and enrichments. JavaScript is a complex language built over almost thirty years, and while we are unable to replicate every piece of functionality that a developer would normally expect while coding, ServiceNow CPQ scripting remains a powerful tool to assist in the dynamic configuration of products.

The capabilities of ServiceNow CPQ scripting are always expanding. Check back to see the most up-to-date features.

Supported operators

Arithmetic operators:

  • +

    Addition

  • -

    Subtraction

  • *

    Multiplication

  • /

    Division

  • %

    Modulus

  • ++

    Increment

  • --

    Decrement

String operators:

  • +

    Concatenation

  • +=

    Addition assignment

Assignment operators:

  • =

    Assignment

  • +=

    Addition assignment

  • -=

    Subtraction assignment

Comparison operators:

  • ==

    Equal to

  • ===

    Equal value and equal type

  • !=

    Not equal to

  • !==

    Not equal value nor equal type

  • >

    Greater than

  • <

    Less than

  • >=

    Greater than or equal to

  • <=

    Less than or equal to

Logical operators:

  • &&

    And

  • ||

    Or

Supported objects

Each object supported can be declared with the following:

  • [ ]

    Array

  • " "

    String

  • ( )

    Number

  • true | false

    Boolean

  • { }, new Map( )

    Map

  • new Date( )

    Date

undefined, NaN, and null are unsupported.

Note: Date objects cannot be returned, but they can be referenced and manipulated with the Date APIs in the Help menu.

Supported keywords

  • var
  • let
  • const
  • new
  • if
  • else if
  • else
  • for
  • for/of
  • return

We do not support while or unconditional for loops with break, because of the risk of infinite loops halting performance.

We do not support functions, as the script itself should be small enough to be considered one function. If your script is long with many conditions and variables, consider creating a managed table and using a table query. For more information about using managed tables and table queries, see Matrix Loader: CSV table upload and Minimizing table queries.

Alternative scripts for unsupported operations

Assignment multiplication and division (/= or *=): number = number * otherNumber;, number = number / otherNumber;

Exponentiation (x**y): Math.pow(x, y);

Type conversion

Convert arrays to strings: Array.toString()

Convert numbers to strings: [number] + ""

Convert numeric strings to numbers: [string] - 0

Note: Strings cannot be treated as arrays, but .length does work for strings.

Type checking

The following returns a Boolean value indicating whether an input is a number: LGK.isNumber(123)

Accessing object properties

You can access the properties of map objects such as cfgRequest in two ways.

objectName.propertyName
//or
objectName["propertyName"]

This is helpful in order to replace large amounts of repetitive code with results from a Table Lookup, since the “propertyName” text could instead be replaced by a variable.

For example, consider a blueprint with the following fields associated with it, and a managed table named shipstatebooleantest.

  • shipState
  • boolean1
  • boolean2
  • boolean3
  • quantity1
  • quantity2
  • quantity3
idshipStatetrueBooleanquantityTestrowQuantity
1Arizonaboolean1quantity11
2Maineboolean2quantity22
3Californiaboolean3quantity33

Instead of having an identical if statement check what shipState is and setting the Boolean values and quantities accordingly, you could instead replace it with only one if statement that sets the values based on the results of a table lookup.

In the following On Configure/Reconfigure script, if the shipState field has a value, the fields that are returned by the lookup function are set. If the shipState field is blank, then all Boolean and quantity fields are set.

if (cfgRequest.shipState.value != "" && cfgRequest.shipState.value != null){
    var fieldMapping = lookup("Select trueBoolean,quantityTest,rowQuantity from shipstatebooleantest where shipState = :value", { "value": cfgRequest.shipState.value });
    console.log(fieldMapping);
    if (fieldMapping != []){
        cfgRequest[fieldMapping[0].trueBoolean].set("value",true);
        cfgRequest[fieldMapping[0].quantityTest].set("value",fieldMapping[0].rowQuantity);
    }
}
else{
    var fieldMapping = lookup("Select trueBoolean,quantityTest,rowQuantity from shipstatebooleantest");
  console.log(fieldMapping);
  for (var row of fieldMapping) {
        cfgRequest[row.trueBoolean].set("value",true);
        cfgRequest[row.quantityTest].set("value",row.rowQuantity);ea
  }
} 

If your instance of ServiceNow CPQ needs functionality not described here, create a support case by using the ServiceNow Support portal. For step-by-step instructions, see Create a case on Now Support for CPQ Customers.
