How does “Two ways a line moves” work on the Find & Recode page?

Change the transactions in Xero edits the document itself — every field echoed back, only the account or one tracking category replaced, and the result re-read to verify it. That path is proven for bills and sales invoices, including paid ones, so those are the only sources edited in place; credit notes and manual journals go by journal until their own edit path is proven the same way. Post a reclassification journal leaves the original untouched and posts a manual journal that reverses the net amount off the old account or tracking and onto the new one — one journal per organisation per date, VAT not moved. It works for every source whatever the payment or lock state of the original, and the journal is the audit trail. Where: Find & Recode (/accounts/find-recode).
