Proposal

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

Negative amount in transaction thread for held expense after paying unheld expense

What is the root cause of that problem?

For expense report case we add - before amount because the amounts are stored using an opposite sign

App/src/libs/TransactionUtils/index.ts

Lines 345 to 351 in b655040

	// Expense report case:
	// The amounts are stored using an opposite sign and negative values can be set,
	// we need to return an opposite sign than is saved in the transaction object
	let amount = transaction?.modifiedAmount ?? 0;
	if (amount) {
	return -amount;
	}

However, when we handle the pay money request and use getReportFromHoldRequestsOnyxData, we are actually creating an ExpenseReport. For 1:1 direct messages, it should instead be an IOUReport.

App/src/libs/actions/IOU.ts

Lines 6451 to 6459 in b655040

	const optimisticExpenseReport = ReportUtils.buildOptimisticExpenseReport(
	chatReport.reportID,
	chatReport.policyID ?? iouReport?.policyID ?? '',
	recipient.accountID ?? 1,
	holdTransactions.reduce((acc, transaction) => acc + transaction.amount, 0) * (ReportUtils.isIOUReport(iouReport) ? 1 : -1),
	getCurrency(firstHoldTransaction),
	false,
	newParentReportActionID,
	);

This is also not consistent with the BE response in case of 1:1 DMs the backend will return an IOUReport

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

We should add a check here isPolicyExpenseChat. The idea is that if it's a policy expense chat, we should build an optimistic expense report using buildOptimisticExpenseReport. If it's not a policy expense chat, then we should build an optimistic IOU report using buildOptimisticIOUReport. This is the same logic we are using here Pseudocode

 const optimisticExpenseReport = isPolicyExpenseChat
        ? ReportUtils.buildOptimisticExpenseReport(
              chatReport.reportID,
              chatReport.policyID ?? iouReport?.policyID ?? '',
              recipient.accountID ?? 1,
              totalAmount,
              getCurrency(firstHoldTransaction),
              false,
              newParentReportActionID,
          )
        : ReportUtils.buildOptimisticIOUReport(recipient.accountID ?? 1, iouReport?.managerID ?? 1, totalAmount, chatReport.reportID, getCurrency(firstHoldTransaction), false);

After this change, this line will evaluate to false, and we'll move to this block, where we'll apply -amount, which will fix the bug

App/src/libs/TransactionUtils/index.ts

Line 337 in b655040

if (!isFromExpenseReport || isFromTrackedExpense) {

Note: This is pseudocode only. We need to test the implementation with multiple test cases, which can be done in the pull request (PR).

What alternative solutions did you explore? (Optional)

We can use buildOptimisticIOUReport here instead of buildOptimisticExpenseReport
