data-policies

ServiceNow data policies enforce field behavior by defining rules in sys_data_policy2 and sys_data_policy_rule, making fields mandatory, read-only, or constrained across forms and records to ensure data integrity.

Yes, you can use sys_dictionary_override to control table schemas, allowing you to shape dictionary definitions and override default field behaviors for specific tables like incident and change_request.

Dictionary rules control table schemas and field definitions via sys_dictionary, while data policies in sys_data_policy2 enforce when fields become mandatory, read-only, or constrained during record transactions.

You can script ServiceNow data policies and dictionary entries using included ES5 examples to create tables, fields, choices, overrides, and complex policy logic across common tables for real-world scenarios.

Yes, this approach manages table schemas via sys_dictionary and enforces data integrity across multiple ServiceNow tables like incident and change_request using data policies and dictionary overrides.

Dictionary overrides may not apply correctly if the sys_dictionary_override configuration does not properly target the inherited field definitions or if data policy rules conflict with the intended field behavior.
