Magento 2 Invoice Capture Options

Question

In Magento 1, you can enable capture options for an invoice by adding

protected $_canCapture = true;

to app\code\core\Mage\Payment\Model\Method\METHODNAME.php

In Magento 2, how can this be done?

I'm trying to do this to the purchase order method so invoices can be created but not marked as paid.

Answer 1

It can be done the same way as Magento 1.

In the payment method class, you can change:

protected $_canCapture = false;

To:

protected $_canCapture = true;
