CargoWise can post exchange-difference (EXX) match lines on a payment receipt. Those lines are accounting adjustments for FX differences. They are not payment allocations that belong on a SAT complemento de pago. Lambda excludes EXX lines from the stamped REP.

​
What that means

  • The payment CFDI covers the real PPD payment allocations that remain after EXX lines are removed.
  • EXX amounts stay in CargoWise accounting; they do not become REP match lines.
  • Omitting EXX is expected behavior, not a missing-line failure.
If the receipt also has ordinary PPD allocations, those still reconcile and stamp under the normal payment complement rules.

​
What it is not

  • Not an FX inventing rule — cross-currency payments still need proven rate or MXN evidence for the lines that do stamp. See Troubleshooting.
  • Not the same as the REP eligibility window, which decides parent inclusion by PostDate days.
