Which statement is true when updating an existing record with the Write Records smart service?

• A. The record ID must correspond to an existing author
• B. You must supply the record's primary key value
• C. All fields must be updated
• D. No mapping is required

Answer: (A)

Updating an existing record with the Write Records smart service requires identifying the exact record to modify by using its ID. That ID must correspond to a record that already exists for the selected record type (for example, an existing author). If the ID does not match an existing record, there is no target to update, and the operation will fail. The Record ID points to the specific row in the data source that you want to update, and the service will apply the mapped field values to that record. You don’t necessarily provide the data source’s primary key value directly; the important part is supplying the Appian Record ID that points to the existing record. You can update only the fields you need, as long as those fields are properly mapped. And some mapping is required to tell the service which fields to update and with which values.
