Appian Senior Developer (ACD101) — Question 8

Your customer wants to change the name of a field of an existing Custom Data Type (CDT) to match a renamed database field.
The CDT is backed by a database entity, whose data store has the Automatically Update Database Schema option disabled. The old column name was BIRTHDATE and the new column name is DATE_OF_BIRTH.
How should you proceed?

Answer options

• A. Download the CDT as XSD, make the appropriate changes, and re-upload the XSD. Verify and publish the data store.
• B. Rename the field in the record type in Appian to automatically update the CDT field.
• C. Rename the field in the CDT in Appian. Verify and publish the data store.

Correct answer: A

Explanation

The correct answer is A because downloading the CDT as an XSD allows for manual changes to the field name, which is necessary since the database schema cannot be automatically updated. Option B is incorrect because it relies on an automatic update feature that is disabled, and Option C does not address the need for the database schema to be updated properly after renaming the field.
