Proposal

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

Expense - Currently opened expense report is not displayed in LHN after returning from Search

What is the root cause of that problem?

When we have an iou report with one transaction the item in search is a transaction type and for transaction case we are opening the transactionThreadReport here

App/src/components/Search/index.tsx

Lines 134 to 135 in b0f810d

	let reportID = SearchUtils.isTransactionListItemType(item) ? item.transactionThreadReportID : item.reportID;

But there is a code here that returns falsey when the report is isOneTransactionThread to exclude it from lhn

App/src/libs/SidebarUtils.ts

Lines 127 to 129 in b0f810d

	if (ReportUtils.isOneTransactionThread(report.reportID, report.parentReportID ?? '0', parentReportAction)) {
	return;
	}

This is to avoid having two lhn items for the same transaction thread because in the case of one transaction in an iou pressing on the iou report opens the only transaction thread as it is the only one (isOneTransactionThread) in it. So we don't need an lhn for isOneTransactionThread case.

What alternative solutions did you explore? (Optional)

This issue doesn't occur when we open a report via report preview because in that case we open the iou report (with one transaction) not the transactionThreadReport therefore we should be consistent and follow the same logic in search page here too.
So, we should open the the report (iou report) instead of transaction thread here when the item is transaction type in here

App/src/components/Search/index.tsx

Lines 134 to 135 in b0f810d

	let reportID = SearchUtils.isTransactionListItemType(item) ? item.transactionThreadReportID : item.reportID;

change it to

        let reportID = item.reportID;

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

The currently opened expense thread is not displayed in LHN
This issue only happens when there is only one expense in the report

What is the root cause of that problem?

When we open the report from the search, we open the transaction thread report. Then after we return from Search, this report is opened but we hide this in LHN if the expense report is the combine report

App/src/libs/SidebarUtils.ts

Line 127 in 4adf0c5

if (ReportUtils.isOneTransactionThread(report.reportID, report.parentReportID ?? '0', parentReportAction)) {

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

We should remove this condition here

App/src/libs/SidebarUtils.ts

Line 127 in 4adf0c5

if (ReportUtils.isOneTransactionThread(report.reportID, report.parentReportID ?? '0', parentReportAction)) {

And in shouldReportBeInOptionList function we should move this condition below the condition here so the transaction thread report of the combine report will only display in LHN if it's opened.

What alternative solutions did you explore? (Optional)

For snapshot transaction item, BE should return an extra field isOneTransactionThread to know if it's one transaction thread or not, and then we will use this here to open the combined report in this case.

let reportID = SearchUtils.isTransactionListItemType(item) && !item.isOneTransactionThread ? item.transactionThreadReportID : item.reportID; 

App/src/components/Search/index.tsx

Lines 134 to 135 in b0f810d

	let reportID = SearchUtils.isTransactionListItemType(item) ? item.transactionThreadReportID : item.reportID;

Updated only to add more explanation to my first solution.

@lanitochka17, I really don't understand this bug report as written in the OP. @luacmartins does this make sense to you? 🤔

[FitseTLT]

@trjExpensify Whenever you open a report it is included in LHN (highlighted lhn item representing it) but in this case if you create an expense where it is the only expense in iou report then when you open it from search the report will not be any lhn item corresponding to it (which was supposed to be the highlighted one in normal cases) 👍

[luacmartins]

Hmm I think this has the same root cause as #45408. Because we are opening the transaction thread in the RHP, we record the last visited report as the thread. Then when we navigate to the LHN we don't see it because we hide the thread if it's a one expense report.

[luacmartins]

I think we can put this issue on hold for #45408.
