Least-Cost Routing
Least-cost routing (LCR) is an option that offers the lowest routing costs available.
LCR uses single-message processing, when it is possible,
to move funds in a single, full-financial message. A full-financial
message moves funds immediately.
When you request least-cost routing, the processor first determines
whether LCR is possible for the transaction. If LCR is possible, the
processor uses single-message processing to accomplish LCR. If the
transaction is enabled for partial authorization, the processor can
process a partial amount instead of the entire requested amount.
IMPORTANT
Least-cost routing is not supported for all features and services.
Some transactions are not supported for single-message processing, either because
they are not applicable or because they could create reconciliation problems.
To find out whether the processor used least-cost routing for a transaction,
see the daily processor report.
