What is a key requirement when creating a custom validation rule in Workday?

When creating a custom validation rule in Workday, it is essential that the rule is based on predefined Workday conditions. This requirement ensures that the validation aligns with the system's existing framework, allowing it to integrate smoothly with Workday's operational logic. By utilizing these predefined conditions, the custom validation can effectively utilize the data structures and rules that Workday has established, which enhances both consistency and reliability in financial reporting.

This approach also means that the validation rules are built atop the foundational logic of Workday, which supports escalation paths and error handling that are already in place. This is crucial for maintaining data integrity and ensuring that the custom rules contribute to the larger picture of financial governance within the organization.
