Custom Fields
Learn how to manage custom fields as one type of reference data
1. What Are Custom Fields
Custom Fields are one type of reference data that lets you add extra fields to assets, accessories, licenses, components, and consumables in AssetLoom. They help you capture organization-specific information that is not included in the default fields.

The Custom Field section is located under the Reference Data section in the Personal Settings page. This page displays all custom fields of all resource types in the system and serves as the central place for managing them.

2. How To Set Up Custom Fields
Step 1: Navigate To The Custom Field Screen
Select the Reference Data in the Configure section on the left-hand side menu sidebar.

On the left menu sidebar, you can view the Custom Fields under the Reference Data.

Step 2: Fill In The Custom Field Form
Click the “New Item” button to open the Custom Field Form.

Now you can fill in the Custom Field Form. Below are some key fields:

Name: Name the custom fields
Resource: Define where this custom field will be applied (Asset, Accessory, License, Component, or Consumable).
Description: Additional information that explains the purpose of this custom field or how it should be used.
Default: Marks this custom field as the default for the selected resource. It becomes the default field when you open the resource creation form.
Field Type: Select the input format for this custom field. AssetLoom supports you with 5 main field types:
- Short Text: Enter a brief text value, such as a code, label, serial reference, or short note.
- Paragraph: Add longer text, such as detailed remarks, instructions, conditions, or internal notes.
- Single Select: Choose one option from a predefined list to keep data consistent.
- Date: Select a date, such as warranty expiry, review date, renewal date, or inspection date.
- Checkbox: Mark a simple yes/no value to make a binary choice.
Step 3: Save The Custom Fields
Once all required fields are filled, click the Create button at the bottom of the form to save the custom field to the system.

Step 4: Review Your Custom Fields
After creating the custom fields, you will be redirected to the Custom Field List, where you can view and manage all your custom fields. If any information needs to be updated, simply click on the custom fields and modify the details as needed.
