PayPal: Remove an external payment recorded on the wrong invoice

See more PayPal Examples

Use the saved external payment record ID. Verify that it belongs to the selected invoice, then remove the bookkeeping entry. The bank transfer itself is unaffected. Record it on the correct invoice as a separate step.
