/vendor/magento/module-eav/Model/Entity/Attribute/ScopedAttributeInterface.php

There are 3 defined scopes

/**
 * @api
 * @since 100.0.2
 */
interface ScopedAttributeInterface
{
    const SCOPE_STORE = 0;

    const SCOPE_GLOBAL = 1;

    const SCOPE_WEBSITE = 2;
}

and here is the DB for entity_type_code

mysql> SELECT entity_type_id, entity_type_code FROM eav_entity_type;
+----------------+------------------+
| entity_type_id | entity_type_code |
+----------------+------------------+
|              1 | customer         |
|              2 | customer_address |
|              3 | catalog_category |
|              4 | catalog_product  |
|              5 | order            |
|              6 | invoice          |
|              7 | creditmemo       |
|              8 | shipment         |
+----------------+------------------+

So above all entities, Which Entity Allows scope attributes.

enter image description here

customer and customer_address Does not support Scope Attribute [Global]

catalog_category and catalog_product Does support Scope Attribute [Default, Website and Store]

So the question is Sales tables does support Scope Attribute ? Because sales tables are stored as flat tables in Magento.

5: order
6: invoice
7: creditmemo
8: shipment

  • customer and customer_address Does not support Scope Attribute [Globle]
  • catalog_category and catalog_product Does support Scope Attribute [Default, Website and Store]

So the question is Sales tables does support Scope Attribute ? Because sales tables are stored as Flat table in Magento

Sales DOES NOT support Scope Attributes.

enter image description here

Confirmation 1 : Check the eav_entity_type table in Magento 2

  • attribute_model and entity_attribute_collection is NULL for sales related entities.
  • Where as Customer Attributes can be created Scope wise.
  • Catalog Attributes can be created Scope wise.

Confirmation 2 : Check getDefaultEntities function in Setup folder, It clears the doubt.

vendor/magento/module-customer/Setup/CustomerSetup.php

            ],
        ];
        return $entities;
    }

In Conformation 2 - getDefaultEntities is Scope wise for Customer Attributes and Catalog as well Categories But Sales DOES NOT support Scope Attributes, It is not defined in Setup.

As per my understanding you can only create custom attribute for below entity types:

  1. Customer (Scope: Global)
  2. customer_address (Scope: Global)
  3. catalog_category (Scope: Default, Website and Store)
  4. catalog_product (Scope: Default, Website and Store)

as when you have a look on eav_entity_type table's column additional_attribute_table and entity_attribute_collection you can see the values for above 4 entity_types only.

And for Customer attribute by default scope is Global (default) so you don't have to set the scope attribute. For rest i.e Catalog Category and Product you can set any scope i.e Global (default), Website or Store

For rest I don't think you can create, but if you want to create extra column for rest of the entity you can use extension attribute feature of M2
