A repeat-to-repeat throughput mapping is a type of repeat mapping
that maps all instances of one repeating field in the input message to all
instances of another repeating field in the target message. Repeat-to-repeat
throughput mapping is an 'any-to-any' mapping that maps an [All] node on the
source side to an [All] node on the target side. This type of mapping is useful
if you need to change individual source values without disrupting the order.
For example, you might want to add tax or apply a discount to each price
in a source message. Other types of repeat mapping are:
- Aggregate (many-to-one) mapping, where all repeats are aggregated into
a single target field.
- Looped assignment (one-to-many) mapping, where one source field is mapped
to many repeats in the target field.
The following steps show you how to create a repeat-to-repeat throughput
mapping.
