Is this configuration option required when an engineer sets up any application?

Create Policy is not required for every IdentityIQ application. In IdentityIQ, provisioning policies are used when the system needs structured forms and field definitions for operations such as account creation, update, delete, enable, disable, or password actions. A Create Policy is specifically relevant when IdentityIQ is expected to create accounts on that target application and needs to collect or calculate the required values for account creation. Many applications may be onboarded initially for aggregation, correlation, governance, certifications, or visibility only, without immediate provisioning. In those cases, a Create Policy is unnecessary. Even in provisioning-enabled environments, not all applications support account creation, and some may support only entitlement changes or account disables. Therefore, Create Policy is an optional provisioning configuration, not a required field for setting up any application.
