Can't create more than one credit memo if order's grand total is 0

[mushketer888]

Preconditions (*)

Magento 2.3.3

Steps to reproduce (*)

1. Crete order with 100% discount on all items and shipping. (Cart rule promo code can be used for that) Grand total (including shipping) must be 0. Order must contain product's quantity atleast as 2
2. Create credit memo and refund order with "Qty to Refund" = 1. ("Return to stock" doesn't affect on this issue)
   

Expected result (*)

1. Be able to refund left ordered/invoiced items (to fully refund order/items)

Actual result (*)

1. Magento 2 doesn't give ability to create additional credit memo

In my opinion the problem lies in Magento\Sales\Model\Order.php canCreditmemo()
and in canCreditmemoForZeroTotal() see HERE

//check if total paid is less than grandtotal
$checkAmtTotalPaid = $totalPaid <= $this->getGrandTotal();

So if totalPaid ==0 and grandTotal ==0 then canCreditmemoForZeroTotal==false

But more precise maybe this code:
$paidAmtIsRefunded = $this->getTotalRefunded() == $totalPaid && $creditmemos;
totalRefunded==0, totalPaid==0 and has credit memos

Is there some patch or workaround for that?

Hi @mushketer888,

Tried to reproduce the issue but step 2 is not clear , Hence Kindly provide steps for Creating credit memo.

Therefore , Added the label 'Needs update'.

Thanks

[mushketer888]

Hi @engcom-Delta
The step 2 is just to create credit memo for order which has discount on all items and shipping with amount of 100% but with less product's quantity that order/invoice has

For example:
order 2 same products (qty=2) with discount of 100% (with shipping discount of 100% too) grandtotal must be 0.00
create creditmemo, but refund only 1 product qty
then try to create one more (second) creditmemo to refund lasting product item - you won't be able to do it
so basically if order's grand total = 0 then you can create only one credit memo, it doesn't check if there's more refundable product's left

Hi @mushketer888,

I tried to reproduce the issue on Magento 2.4.2 as per provided steps & comments.
in fact, i have not able to create credit memo for the order which has 100% discount( cart items + shipping).
Kindly find the attached screenshots for reference. Hence issue marked as 'Issue confirmed'

order#

Note: Create Credit Memo option is missing after refunded 1 item & order status closed

Steps followed:

1. Create cart rule promo with 100% discount with quantity + shipping method
2. order 2 same products (qty=2) with discount of 100% (with shipping discount of 100% too) grandtotal must be 0.00
   create credit memo, but refund only 1 product qty
3. then try to create one more (second) creditmemo to refund lasting product item - you won't be able to do it
   so basically if order's grand total = 0 then you can create only one credit memo, it doesn't check if there's more refundable product's left.
4. Observe that you are not able to create second credit memo.
