Matching multiple source names

If more than one source name for a map has a wildcard, you can use the first source with that wildcard to set the wildcard value for the other sources required by the same map instance.

For example, consider a business using an order system that requires a credit check for all orders. Orders that pass the credit check need to be confirmed; the business does not want to mismatch an order with the wrong credit check.

In this example, the order message is a source trigger. When a new order arrives, its message identifier is used as the value of the wildcard and CreditCheck will not run until a credit report message with the same message identifier arrives.
