There's a way of checking a transaction's history, wineryfinman.
You can run the Audit Log report to check what happened or what caused the payments to be applied to a single vendor. Here's how:
- Go to Gear or Settings ⚙ icon and select Audit Log.
- Click Filter.
- Use the fields on the Filter panel to choose the appropriate User, Date, or Events filter to narrow the results.
- Select Apply.
- Look for the transaction that has an incorrect vendor, then click the View link under the History column.
