All,  Schedule lines are defined as 1:* cardinality in my target schema. However after the message mapping it's returned as single element instead of array. Can you guys help on how to convert it as Array? Delivery date/ Quantity of the schedule line schema are mapped to source item fields. 

Target XSD Schema:

You need to enable streaming in your XML to JSON converter with the appropriate settings.  See the help URL for more information.  https://help.sap.com/docs/cloud-integration/sap-cloud-integration/how-streaming-in-xml-to-json-conve...

Thanks, Ryan. I don't see any steps/details to enable the streaming. Do you mind listing the steps here?

@SG141 please see the screenshot for an example and you would need to add an entry for every complex type you want to be represented as an array. Note there is an option for "All" but that literally changes everything but the root to arrays.
