Note: This release is in preview. Features described here don’t become generally available until the latest general availability date that Salesforce announces for this release. Before then, and where features are noted as beta, pilot, or developer preview, we can’t guarantee general availability within any particular time frame or at all. Make your purchase decisions only on the basis of generally available products and features.

Create a Custom Object

In this step, you create a custom object called Book with one custom field called Price.
Prerequisites:

A Salesforce account in a sandbox Professional, Enterprise, Performance, or Unlimited Edition org, or an account in a Developer org.

For more information about creating a sandbox org, see “Sandbox Types and Templates” in Salesforce Help. To sign up for a free Developer org, see the Developer Edition Environment Sign Up Page.

  1. Log in to your sandbox or Developer org.
  2. From your management settings for custom objects, if you’re using Salesforce Classic, click New Custom Object, or if you’re using Lightning Experience, select Create | Custom Object.
  3. Enter Book for the label.
  4. Enter Books for the plural label.
  5. Click Save.
    Ta dah! You’ve now created your first custom object. Now let’s create a custom field.
  6. In the Custom Fields & Relationships section of the Book detail page, click New.
  7. Select Number for the data type and click Next.
  8. Enter Price for the field label.
  9. Enter 16 in the length text box.
  10. Enter 2 in the decimal places text box, and click Next.
  11. Click Next to accept the default values for field-level security.
  12. Click Save.
You've created a custom object called Book, and added a custom field to that custom object. Custom objects already have some standard fields, like Name and CreatedBy, and allow you to add other fields that are more specific to your implementation. For this tutorial, the Price field is part of our Book object, and the Apex class you’ll write in the next step accesses it.
