Save and display ui_component's custom field

Question

I've added custom text box to source form using below code.

<field name="delivery_time" formElement="input" sortOrder="70">
            <settings>
                <dataType>text</dataType>
                <label translate="true">Delivery Time</label>
            </settings>
</field>

To save this field value I'm observing event controller_action_inventory_populate_source_with_data.

I tried below in observer,

$request = $observer->getEvent()->getRequest();
$requestData = $request->getParam('general', []);
$deliveryTime =  $requestData['delivery_time'];

I tried below code but it's not working,

$request->setParam('delivery_time',$deliveryTime);

$request->setPostValue('delivery_time',$deliveryTime);

I've created new column with delivery_time to table.

None of above is working Any idea ?

Any help will be appreciate. Thanks in advance.

To save this you have to create extension attribute for your entity.

https://devdocs.magento.com/guides/v2.3/extension-dev-guide/attributes.html

Check above to know how to create those.

Than you can use in observer like, setter and getter methods like getDeliveryTime and setDeliveryTime.

Hope it will help to solve your issue.
