Explanation of Change

When splitting an existing expense, the newly created split transactions were not temporarily highlighted in the expense report list.

There were two gaps:

  1. Write sideupdateSplitTransactionsFromSplitExpensesFlow called Navigation.dismissModalWithReport without first registering the new split transaction IDs via addPendingNewTransactionIDs. The normal create path does this via navigateAfterExpenseCreate, but the split-update path skipped it entirely.

  2. Read sideMoneyRequestReportActionsList called useNewTransactions with only 2 arguments, so the pendingNewTransactionIDs metadata fallback (which highlights transactions already present on mount) was never exercised.

Fix:

  • In SplitTransactionUpdate.ts, before the navigation call, loop over the split expenses and call addPendingNewTransactionIDs for each transaction ID. Skipped for reverse-split and last-transaction-in-report cases. This now also covers splitting from the Search page, where navigateBackToLastSuperWideRHPScreen is used instead of dismissModalWithReport.
  • In MoneyRequestReportActionsList.tsx, subscribe to REPORT_METADATA via pendingNewTransactionIDsSelector and pass all 5 arguments to useNewTransactions, mirroring what MoneyRequestReportPreview already does.

Fixed Issues

$ #91679
PROPOSAL: #91679 (comment)

Tests

  1. Open an expense report with at least one expense.
  2. Click More > Split > Save on an expense.
  3. Verify the split expenses are temporarily highlighted (brief yellow/blue flash) in the expense report list after the split completes.
  4. Verify the original expense is no longer visible in the list.
  5. Verify no JS console errors appear.
  • Verify that no errors appear in the JS console

Offline tests

N/A — split expense saving requires network. The highlight logic is optimistic (fires before the API response), so offline state does not affect it.

QA Steps

  1. Go to staging.new.expensify.com.
  2. Open an expense report with at least one expense.
  3. Click More > Split > Save on an expense.
  4. Verify the new split expense rows are temporarily highlighted after splitting.
  5. Verify no JS console errors appear.
  • Verify that no errors appear in the JS console

PR Author Checklist

  • I linked the correct issue in the ### Fixed Issues section above
  • I wrote clear testing steps that cover the changes made in this PR
    • I added steps for local testing in the Tests section
    • I added steps for the expected offline behavior in the Offline steps section
    • I added steps for Staging and/or Production testing in the QA steps section
    • I added steps to cover failure scenarios (i.e. verify an input displays the correct error message if the entered data is not correct)
    • I turned off my network connection and tested it while offline to ensure it matches the expected behavior (i.e. verify the default avatar icon is displayed if app is offline)
    • I tested this PR with a High Traffic account against the staging or production API to ensure there are no regressions (e.g. long loading states that impact usability).
  • I included screenshots or videos for tests on all platforms
  • I ran the tests on all platforms & verified they passed on:
    • Android: Native
    • Android: mWeb Chrome
    • iOS: Native
    • iOS: mWeb Safari
    • MacOS: Chrome / Safari
  • I verified there are no console errors (if there's a console error not related to the PR, report it or open an issue for it to be fixed)
  • I followed proper code patterns (see Reviewing the code)
    • I verified that any callback methods that were added or modified are named for what the method does and never what callback they handle (i.e. toggleReport and not onIconClick)
    • I verified that comments were added to code that is not self explanatory
    • I verified that any new or modified comments were clear, correct English, and explained "why" the code was doing something instead of only explaining "what" the code was doing.
    • I verified any copy / text shown in the product is localized by adding it to src/languages/* files and using the translation method
    • I verified all numbers, amounts, dates and phone numbers shown in the product are using the localization methods
    • I verified any copy / text that was added to the app is grammatically correct in English. It adheres to proper capitalization guidelines (note: only the first word of header/labels should be capitalized), and is either coming verbatim from figma or has been approved by marketing (in order to get marketing approval, ask the Bug Zero team member to add the Waiting for copy label to the issue)
    • I verified proper file naming conventions were followed for any new files or renamed files. All non-platform specific files are named after what they export and are not named "index.js". All platform-specific files are named for the platform the code supports as outlined in the README.
    • I verified the JSDocs style guidelines (in STYLE.md) were followed
  • If a new code pattern is added I verified it was agreed to be used by multiple Expensify engineers
  • I followed the guidelines as stated in the Review Guidelines
  • I tested other components that can be impacted by my changes (i.e. if the PR modifies a shared library or component like Avatar, I verified the components using Avatar are working as expected)
  • I verified all code is DRY (the PR doesn't include any logic written more than once, with the exception of tests)
  • I verified any variables that can be defined as constants (ie. in CONST.ts or at the top of the file that uses the constant) are defined as such
  • I verified that if a function's arguments changed that all usages have also been updated correctly
  • If any new file was added I verified that:
    • The file has a description of what it does and/or why is needed at the top of the file if the code is not self explanatory
  • If a new CSS style is added I verified that:
    • A similar style doesn't already exist
    • The style can't be created with an existing StyleUtils function (i.e. StyleUtils.getBackgroundAndBorderStyle(theme.componentBG))
  • If new assets were added or existing ones were modified, I verified that:
    • The assets are optimized and compressed (for SVG files, run npm run compress-svg)
    • The assets load correctly across all supported platforms.
  • If the PR modifies code that runs when editing or sending messages, I tested and verified there is no unexpected behavior for all supported markdown - URLs, single line code, code blocks, quotes, headings, bold, strikethrough, and italic.
  • If the PR modifies a generic component, I tested and verified that those changes do not break usages of that component in the rest of the App (i.e. if a shared library or component like Avatar is modified, I verified that Avatar is working as expected in all cases)
  • If the PR modifies a component related to any of the existing Storybook stories, I tested and verified all stories for that component are still working as expected.
  • If the PR modifies a component or page that can be accessed by a direct deeplink, I verified that the code functions as expected when the deeplink is used - from a logged in and logged out account.
  • If the PR modifies the UI (e.g. new buttons, new UI components, changing the padding/spacing/sizing, moving components, etc) or modifies the form input styles:
    • I verified that all the inputs inside a form are aligned with each other.
    • I added Design label and/or tagged @Expensify/design so the design team can review the changes.
  • If a new page is added, I verified it's using the ScrollView component to make it scrollable when more elements are added to the page.
  • I added unit tests for any new feature or bug fix in this PR to help automatically prevent regressions in this user flow.
  • If the main branch was merged into this PR after a review, I tested again and verified the outcome was still expected according to the Test steps.

Register each new split transaction ID via addPendingNewTransactionIDs
before navigating away, so MoneyRequestReportActionsList can identify
and highlight them on first load via the pendingNewTransactionIDs path.

Covers all three navigation branches:
- dismissModalWithReport (normal workspace split)
- isSelfDMSplit (selfDM → workspace split)
- isSearchPageTopmostFullScreenRoute (split from search page)

Skipped for isReverseSplitOperation (no new transactions) and
isLastTransactionInReport (report is being emptied, fallback nav).

On the read side, subscribe MoneyRequestReportActionsList to
REPORT_METADATA via pendingNewTransactionIDsSelector and pass all 5
arguments to useNewTransactions, enabling the metadata fallback path
that highlights transactions already present on mount.

  1. Navigate to a workspace chat / expense report.
  2. Create an expense.
  3. Open the expense, click More > Split > Save.

Can you consolidate these steps?

  1. Open an expense report with single expense
  2. Click More > Split > Save

Also please resolve conflicts @aswin-s


const targetReportID = params.expenseReport?.reportID ?? String(CONST.DEFAULT_NUMBER_ID);

Why do we need isSearchPageTopmostFullScreenRoute here? With it, expenses are not highlighted when splitting in Search page.

🤖 Help site review: no docs changes required.

This PR is a transient UI behavior fix — it registers the new split transaction IDs (addPendingNewTransactionIDs) and wires MoneyRequestReportActionsList to useNewTransactions so the newly created split rows briefly highlight in the expense report list after splitting. It only touches src/libs/actions/IOU/SplitTransactionUpdate.ts and a test file; there are no changes to feature names, tab names, settings, button labels, or any documented workflow.

The relevant help article, Split Expenses, documents how to split, edit, and revert expenses (the More > Split > Save flow). The brief highlight flash is a visual polish detail that the article does not describe and does not need to — the documented steps and outcomes are unchanged.

No draft PR was created since no help site updates are needed.

@aswin-s, if you believe a help site update is warranted (for example, to document this highlight behavior), let me know and I'll create the draft PR.
