Proposal

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

Track expense - Edited amount is not reflected correctly in amount editor on confirmation page

What is the root cause of that problem?

We are taking the modifiedAmount from the trackExpense when we create draft transaction on submit it to someone

App/src/libs/ReportUtils.ts

Lines 8037 to 8046 in 4a25c36

	IOU.createDraftTransaction({
	...transaction,
	actionableWhisperReportActionID: reportActionID,
	linkedTrackedExpenseReportAction,
	linkedTrackedExpenseReportID: reportID,
	created,
	modifiedCreated: undefined,
	amount,
	currency,
	comment,

So in IOUStepAmountPage we only update only amount (not modifiedAmount) of the transaction if the action is not editing

App/src/pages/iou/request/step/IOURequestStepAmount.tsx

Line 170 in 4a25c36

IOU.setMoneyRequestAmount(transactionID, amountInSmallestCurrencyUnits, currency || CONST.CURRENCY.USD, shouldKeepUserInput);

So in confirmation page we will see this new amount we updated but when reopen the amount page it will show us modifiedAmount which has not been updated

App/src/libs/TransactionUtils/index.ts

Lines 337 to 340 in 4a25c36

	if (!isFromExpenseReport || isFromTrackedExpense) {
	const amount = transaction?.modifiedAmount ?? 0;
	if (amount) {
	return Math.abs(amount);

it prioritize modifiedAmount if over amount if it exists

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

We should mimic the setup we have for create expense (because submit it to someone is basically creating an expense from an existing some sort of expense template) so when we create a draft transaction increateDraftTransactionAndNavigateToParticipantSelector whether it is for submit, categorize or share we should reset modifiedAmount to undefined so that IOURequestStepAmount will have one source of truth amount same as what we have for creation of a new request.
We need to reset modifiedAmount on the draft transaction here

        currency,
        modifiedAmount: undefined,

What alternative solutions did you explore? (Optional)

Proposal

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

The amount is $20, while it shows $30 on the confirmation page.

What is the root cause of that problem?

If the original amount is 100
When editing the track expense to 200, we will update modifiedAmount: -200, amount: -100

We're showing the amount on confirmation page

App/src/pages/iou/request/step/IOURequestStepConfirmation.tsx

Line 640 in 47b6811

iouAmount={Math.abs(transaction?.amount ?? 0)}

But on amount page, we use modifiedAmount

App/src/pages/iou/request/step/IOURequestStepAmount.tsx

Line 87 in 47b6811

const {amount: transactionAmount} = ReportUtils.getTransactionDetails(currentTransaction) ?? {amount: 0};

App/src/libs/TransactionUtils/index.ts

Lines 358 to 360 in 47b6811

	const amount = transaction?.modifiedAmount ?? 0;
	if (amount) {
	return Math.abs(amount);

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

We should update modifiedAmount if it's the draft transaction in

App/src/libs/actions/IOU.ts

Lines 404 to 406 in 47b6811

	function setMoneyRequestAmount(transactionID: string, amount: number, currency: string, shouldShowOriginalAmount = false) {
	Onyx.merge(`${ONYXKEYS.COLLECTION.TRANSACTION_DRAFT}${transactionID}`, {amount, currency, shouldShowOriginalAmount});
	}

function setMoneyRequestAmount(transactionID: string, amount: number, currency: string, shouldShowOriginalAmount = false) {
    Onyx.merge(`${ONYXKEYS.COLLECTION.TRANSACTION_DRAFT}${transactionID}`, {amount, currency, shouldShowOriginalAmount, modifiedAmount: amount});
}
