81.An Adobe Commerce developer is tasked with adding the parent order's increment
id to creditmemos fetched through
Magento\Sales\Model\Order\CreditmemoRepository.
To implement this, they choose to create an extension attribute and use the join
directive as follows:
&lt;config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespac
eSchemaLocation="urn:magento:framework:Api/etc/extension_attributes.xsd"&gt;
&lt;extension_attributes for="Magento\Sales\Api\Data\CreditmemoInterface"&gt;
&lt;attribute code="order_increment_id" type="string"&gt;
&lt;join reference_table="sales_order" reference_field="entity_id"
join_on_field="order_id"&gt;
&lt;field&gt;increment_id&lt;/field&gt;
&lt;/join&gt;
&lt;/attribute&gt;
&lt;/extension_attributes&gt;
&lt;/config&gt;
After a few tests, the developer realizes that the development is not working as
expected and that the creditmemos fetched do not contain the increment id.
What is the reason for this?
A. The join directive for extension attributes does not exist so it is simply ignored by
Magento and nothing gets added.
B. The join directive only works for getList() calls, in this case the creditmemos are
fetched using get().
C. The fields used for the join are inverted reference_field should have contained
order_id and join_on_field should have contained entity_id.
D. The fields used for the join directive should use left join for a successful match.
