Map data using custom functions

Last update: Fri Feb 13 2026 00:00:00 GMT+0000 (Coordinated Universal Time)

You can create custom functions in the Functions area of Fusion. You then add these functions to your scenarios in the form of an Adobe App Builder module.

Because custom functions work through Adobe App Builder, your organization must have an Adobe App Builder license to use them.

Custom functions, like most scenario elements, are owned by teams.

Workfront Fusion also includes built-in functions that allow you to create simple or complex formulas. These functions cover a wide variety of use cases, including functions for arrays, strings, numbers, and data from previous modules.

For information and instructions on built-in functions, see Map an item using built-in functions.

Configure a custom function

Custom functions are configured in the Functions area of Workfront Fusion. After a function is configured, you can add it to a scenario using the Adobe App Builder connector.

Initialize your runtime environment

Before you can create custom functions, you must initialize your runtime environment. This needs to be done only if your team does not have any custom functions.

IMPORTANT
Initialization can be performed only be a user with access to Adobe App Builder, either a developer or a system administrator within the IMS organization.
After initialization is complete, all users on the team where initialization was performed are able to create and use functions.

  1. Click the Functions Functions icon tab in the left panel.

    If you have not yet configured your runtime, you see the message “Runtime environment not configured.”

  2. Click Initialize runtime.

    After some time, a Functions list appears, with two sample functions.

Create a custom function

After your runtime environment is configured, you can begin creating custom functions.

IMPORTANT

  • Your custom function must be a JavaScript function.

  • Your custom function must return an object.

  • After you create a custom function, you cannot:

    • Change its name
    • View the default parameter values

  1. Click the Functions Functions icon tab in the left panel.

  2. Click Add function.

  3. Enter a name for the custom function.

    You will not be able to change this name later.

  4. Enter the code for the function.

  5. For each default parameter value you want to add, click Add Parameter and enter the parameter name and default value.

    You can override default parameters when adding the function to a scenario.

  6. Click Save

Add a custom function to a scenario

To add a custom function to a scenario, use the Adobe App Builder connector.
