Add repetition settings to existing attributes to resolve attribute values from collections.
Add an attribute that serves as the repetition source.
The value setting Type for the repetition source attribute must be Collection.
As an example, consider the following attribute that retrieves a collection of payment transactions from a service response. This attribute will serve as the repetition source for a repeating attribute that gets a transaction amount.
A repeating attribute requires a repetition source that points to a collection. To get values from each repetition of the collection, the repeating attribute must have a resolver set to Current Repetition Value.
You can also use repeating attributes in named conditions and named processors. If an attribute uses a named condition or value processor, any repeating attributes referenced in the condition or value processor must have the same repetition source as the attribute itself.
