What happens when you select the Key option for a data source attribute?
A. Transactions with the same key attributes cannot be loaded.
B. The attribute is hidden from users.
C. Transactions are sorted by the attribute.
D. Values are required for the attribute.
Correct Answer: A
Select if you want to activate the duplicate transaction check process. The Key setting is a way to uniquely identify a record in the database. You can select one or more attributes as Keys for the duplicate check. The Transaction Import will not load a file if the file contains one or more transactions that match a Key that has already been loaded.
