The map rule on CustomerEntry(s) uses the
CONTAINSERRORS function to check
if the entire List contains any errors. If List contains an error, no output is
produced. If List does not contain errors, the Customer(s) will be mapped to
CustomerEntry(s).
The result is no output, because List does contain an error - the third Customer
record is invalid.
