問題文
A single Data Mapper Extract must return account fields and, separately, the current user's related task counts from a different object, as two nodes in one JSON. How is this configured?
選択肢
- Switch to a Load, because only Load can output more than one object's data at a time per call.
- It is impossible; a Data Mapper Extract can only ever query one object, so two mappers must always be called in turn.
- Use a Calculation Matrix, because combining two objects into one JSON is a lookup-table task for those two objects now.
- Add multiple extract steps in the one Data Mapper, each targeting its object, and map each into its own output node.
