Fields Configuration 

Order 

This option is used to configure a custom column order.

use Oro\Bundle\EntityConfigBundle\Metadata\Attribute\ConfigField;

/**
 * @var string
 */
#[ConfigField(
    defaultValues: [
        'importexport' => ['order' => 100]
    ]
)]
protected $field;

Identity 

The fields with this option are used to identify (search) the entity. It is possible to use multiple identity fields for one entity.

use Oro\Bundle\EntityConfigBundle\Metadata\Attribute\ConfigField;

/**
 * @var string
 */
#[ConfigField(
    defaultValues: [
        'importexport' => ['identity' => true]
    ]
)]
protected $field;

Excluded 

The fields with this option cannot be exported.

use Oro\Bundle\EntityConfigBundle\Metadata\Attribute\ConfigField;

/**
 * @var string
 */
#[ConfigField(
    defaultValues: [
        'importexport' => ['excluded' => true]
    ]
)]
protected $field;

Full 

All the fields of the related entity are exported. The fields with the [Excluded](#excluded) option are skipped. If full is set to false (the default value), only the fields with an identity will be exported.

use Oro\Bundle\EntityConfigBundle\Metadata\Attribute\ConfigField;

/**
 * @var string
 */
#[ConfigField(
    defaultValues: [
        'importexport' => ['full' => true]
    ]
)]
protected $field;
