Proposal

Please re-state the problem that we are trying to solve in this issue.

Merchant is not set to (none) when creating the scan request offline. Also, the error is not shown when coming back online after modifying the request.

What is the root cause of that problem?

We do not set the (none) merchant value optimistically when placing the scan money request. The RBR is displayed if the value is set to (none), which is set on the API response of RequestMoney API call (which doesn't happen when online).

What changes do you think we should make in order to solve the problem?

When creating an optimistic transaction, we should check if it's a scan transaction, and if so – set "none" instead of the default "Request" in the merchant (using constants and polishing the code a bit, but the idea is understandable):

merchant: merchant || (!!receipt?.state ? '(none)' : CONST.TRANSACTION.DEFAULT_MERCHANT),

App/src/libs/TransactionUtils.ts

Line 69 in 030cfe1

merchant: merchant || CONST.TRANSACTION.DEFAULT_MERCHANT,

Note: There is another issue happening – the optimistic transaction report gets replaced when coming back online, which leads to an error if the request created online optimistically is opened when coming back online. It will be fixed in #31411 – asked and got a confirmation here. Therefore, we may want to hold this issue until that one is done.

What alternative solutions did you explore? (Optional)

Proposal

Please re-state the problem that we are trying to solve in this issue.

1. When creating a scan money request with an empty merchant while offline, the merchant field shows Request instead of (none)
2. After updating the amount, there is no error message and RBR shown for the merchant even though it's actually empty.

What is the root cause of that problem?

1. When we create a scan request, we optimistically set the merchant to Request if it's empty.
   

   App/src/libs/TransactionUtils.ts

   Line 69 in 276b007

   merchant: merchant || CONST.TRANSACTION.DEFAULT_MERCHANT,

It's to fix this issue #28380 where BE response will return Request if the merchant is empty, so we align the optimistic data with the BE response. But now, the BE response return (none) if the merchant sent to the API is empty.

2. When we update the amount (or other field), it will stop the smart scan and will show an error if there is an empty required field, such as the merchant field.
   

   App/src/libs/TransactionUtils.ts

   Lines 135 to 138 in 276b007

   	if (Object.hasOwn(transactionChanges, 'amount') && typeof transactionChanges.amount === 'number') {
   	updatedTransaction.modifiedAmount = isFromExpenseReport ? -transactionChanges.amount : transactionChanges.amount;
   	shouldStopSmartscan = true;
   	}

   
   

   App/src/components/ReportActionItem/MoneyRequestView.js

   Lines 161 to 165 in 276b007

   	let hasErrors = false;
   	if (hasReceipt) {
   	receiptURIs = ReceiptUtils.getThumbnailAndImageURIs(transaction);
   	hasErrors = canEdit && TransactionUtils.hasMissingSmartscanFields(transaction);
   	}

   
   

   App/src/libs/TransactionUtils.ts

   Lines 372 to 374 in 276b007

   	function hasMissingSmartscanFields(transaction: OnyxEntry<Transaction>): boolean {
   	return Boolean(transaction && hasReceipt(transaction) && !isDistanceRequest(transaction) && !isReceiptBeingScanned(transaction) && areRequiredFieldsEmpty(transaction));
   	}

However, as we optimistically set the merchant to Request, the error won't show.

What changes do you think we should make in order to solve the problem?

The merchant will detect (none) as an empty merchant, so my suggestion is to make sure whether it's expected that the BE now returns (none) for an empty merchant or it should be Request like in #29118.

If it's expected that it now returns (none), we can revert #29118 and adjust the code a little bit by replacing the empty string with (none).

-const defaultMerchant = !receipt || Object.keys(receipt).length === 0 ? CONST.TRANSACTION.DEFAULT_MERCHANT : '';
+const defaultMerchant = !receipt || Object.keys(receipt).length === 0 ? CONST.TRANSACTION.DEFAULT_MERCHANT : CONST.TRANSACTION.PARTIAL_TRANSACTION_MERCHANT;

merchant: merchant || defaultMerchant,

@mountiny given the changes you're making, is this issue going to be obsolete?

[mountiny]

I am not 100% sure, this Pr is handling the manual requests only not the scan case #32222

I think the solutions from @paultsimura and @bernhardoj are valid for this problem
