問題文
An external order table is exposed as an external object. Each external order row carries the customer number that the org already stores in a unique external identifier field on the account, and each external order line row carries the key of its order. Which relationship design connects them?
選択肢
- Relate the external order rows to accounts with an indirect lookup that matches the customer number against the unique external identifier field on the account, and relate the order lines to the orders with an external lookup.
- Use a standard lookup and populate it with the account's record identifier in a nightly job.
- Use a master-detail relationship from the external order rows to the account.
- Create a formula field on the external order rows that returns the customer number, and build a custom report type that joins the external rows to accounts on that formula, so that no relationship has to be defined and the external rows can still be listed next to the account.
