Hi, @sankar1061, I've checked described issue on the fresh installation with latest 2.2-develop branch and seems all works as expected. I've tried to simulate two situations:

1. partial invoice & partial refund
   

2. full invoice & partial refund
   

In both cases, the order is still in the Processing status and as you can see there is a possibility to create another invoice or refund.

Did you have some installed extensions? Also, please, provide debug and exception logs.

Note: if you are using Braintree sandbox account, you can't perform online refunds, the capture transaction should be submitted for a settle manually by using Braintree SDK. For more details, please, see Braintree documentation.

Hi @joni-jones,
We have download the module(magento 2.2.0) and fresh installed. And we have checked the same in _Check / Money order_ payment. But order status changed the closed status and hide the _Credit Memo_ button. Please refer the screen shot

[joni-jones]

I've checked with Check / Money order and the order in the Processing state and partial credit memo is available:

Please, provide exception log or PHP error log.

We have download the module(magento 2.2.0)

Is it 2.2.0-preview branch? If not, how you download 2.2.0, it's not published yet.

Hi @joni-jones,
We have checked and does not generated exception log or php error log. And we have wrongly mentioned Magento version. We have used the

Magento ver. 2.3.0-dev

. So please check the same in Magento ver 2.3.0-dev module.

As expected:

Does anyone know what exactly was changed in 2.3.x to fix this issue? If it is possible to temporarily port that change into 2.2.x, that would be wonderful.

After upgrading to 2.3.1, and switching from deprecated authorize.net MD5 based hash direct post to SHA-512 signature key method, I find that partial refunds are no longer supported again. Old module used to have settings of protected $_canRefundInvoicePartial = true; at _vendor/magento/module-authorizenet/Model/Directpost.php:68_. Anyone be kind enough to suggest what and how to extend module-authorizenet-acceptjs to support partial refunds? I have also submitted a question to magento.stackexchange.com
