In a parent FlexCard with a Datatable relationship to a child, which data node expression returns all parent records for the child to consume?

• A. {recordId}
• B. {Params.records}
• C. {records}
• D. {records[0]}

Answer: (C)

When a child FlexCard needs to work with its related parent records, the data node expression that provides the entire set of parent records in the current context is {records}. This delivers the full collection of parent rows for the child to consume, enabling it to iterate or apply logic across all related parents. Using a single ID ({recordId}) or a specific element ({records[0]}) gives only one item, and {Params.records} would only work if such a parameter was explicitly passed. So {records} is the correct expression because it exposes the complete parent dataset for the child to use.
