[youssef-lr]

Part of the Manual Expense Merging in NewDot project

Main issue: https://github.com/Expensify/Expensify/issues/496985
Doc section: https://docs.google.com/document/d/1RXJyOVsX2AgKWNViLSxNm3PH2bSnJCuo6K_jcOxUGuo/edit?tab=t.0#bookmark=id.d4udct66dw0x
Project:

Feature Description

Implement the frontend section of the design doc allowing manually merging two expenses from the expense view, report view, and the Reports page.

Manual Test Steps

https://docs.google.com/document/d/1bQM6A13GZsrzsx7H9Q6wmbbf-1cwcu2qBM1HXpWABzw/edit?tab=t.0#heading=h.x1tkdmajx2wc

Automated Tests

1. Add tests for making the API call and verifying optimistic data have been set properly. Mock data for MERGE_TRANSACTION{transactionID} key, mock the API call and then verify:

• Original transaction is updated
• If single expense report, the report was deleted
• Other transaction is deleted
• Violations of original transaction are deleted

2. Update test of ReportSecondaryActionUtilsTest by adding test cases of:

• Merging two cash expenses: merge option should show up
• Merging two card expenses: merge option should not show up
• Merging cash/card expenses: merge option should show up

Quick update:
Today: I spun up a PR here #65596. Currently, it only contains routes of merging transaction + init pages.
Tomorrow: I will start to add "Merge" menu into secondary action in the expense view

Quick update:
Today: I added "Merge" to secondary actions + display skeleton and empty state for list page
Tomorrow: I'm awaiting GetTransactionsForMerging API command to be deployed or a response example of this API so I can mock data in FE and complete the list page.

Quick update: I've done the merge list page. Tomorrow I will implement receipt review page
