How are the methods setAdjustmentPositive(), getAdjustmentPositive(), setAdjustmentNegative(), getAdjustmentNegative() of the \Magento\Sales\Model\Order\Creditmemo class used?

Implementation

setAdjustmentPositive()

Bug: the setAdjustmentPositive() and setAdjustmentNegative() methods of the \Magento\Sales\Model\Order\Creditmemo class wrongly use the \Magento\Sales\Model\Order's getGrandTotal() method instead of the getBaseGrandTotal() when an adjusment is in percent, so it lead to a wrong calculation result
