A looped assignment mapping is a two-sided mapping from a non-repeatable source element to an [All] node on the target side. This type of mapping is useful if you want to map fixed input information to a number of instances on the target side. For example, a source message represents an order with a number of items, but a single field containing the name of the supplier. The target database requires the supplier name to be included with each item. The following steps show you how to create a looped assignment mapping.
