# Objects and fields supported by Custom Logic

> Lists objects and fields supported by the Custom Logic feature.

Lists objects and fields supported by the Custom Logic feature.

You can use fields from both base and joined objects, up to two levels deep, in decision tables, decision trees, or functions. The available objects and fields depend on the custom logic and object type.

For example, when creating a decision table for the Invoice object, you can define conditions or mutations not only on Invoice fields but also on fields from the related Account object.

## Supported base and joined objects

The following table lists the supported base and joined objects of each custom logic type:

<table>
  <tr>
    <th>
      Base object
    </th>

    <th>
      Joined object
    </th>

    <th>
      Decision table
    </th>

    <th>
      Decision tree
    </th>

    <th>
      Function
    </th>
  </tr>

## Supported fields

Refer to the respective articles for details about the supported fields of each base or joined object. For example, see the Account fields supported by Custom Logic article for the supported fields of the Account and Parent Account objects.

The following table lists the circumstances under which object fields are used in custom logic, including where fields appear in each custom logic.

<table>
  <tr>
    <th />

    <th>
      Decision table
    </th>

    <th>
      Decision tree
    </th>

    <th>

    </th>
  </tr>

  <tr>

    <td>

    <td>
      In function bodies
    </td>
  </tr>

  <tr>
    <td>
      Mutate field values
    </td>

    <td>
      In **Result**

    <td>

Custom Logic supports custom fields on all objects under both circumstances. However, certain standard fields on standard objects are not supported under one or either of these circumstances. For a complete list of supported standard fields of each object, see the corresponding sub-article.
