magento2 – What is the use of “hasForcedCanCreditmemo” method in magento 2?

I have found this method in Magento2/vendor/magento/module-sales/Model/Order.php

        if ($this->hasForcedCanCreditmemo()) {
            return $this->getForcedCanCreditmemo();
        }
   

I am not much sure about this method what its use in this file, i did not find any reference in magento code for this method.

any thoughts on this ?
