What are item level mapping and data point mapping in a dynamic grid?

You can map multiple sources for a single target item in a dynamic grid, but depending on the needs of your study, there are two ways to do it.

• Item level: At this mapping level, items are shared between source and target, and all their attributes will remain the same. In the case of nested items, only the top level item can be selected, making all nested items automatically selected as well.
• Data point: At this mapping level, items are not shared between source and target, and all their attributes must be designed on the dynamic grid itself. In the case of nested items, you can select an individual nested item instead of the top item that contains it.
