What creates or edits critical errors and warning messages for transactions in Workday?

The process of creating or editing critical errors and warning messages for transactions in Workday is primarily done through maintaining custom validations. Custom validations allow organizations to define specific rules and conditions that data must meet to ensure compliance and accuracy within the system. When certain criteria are not met, the system generates error or warning messages that alert users to potential issues before a transaction can be processed. This capability is essential for maintaining data integrity and operational efficiency, especially in procure-to-pay processes where accurate data is crucial for financial operations.

The other options, while important in their own right, do not directly pertain to the creation or modification of the error and warning messaging system. Running financial reports is focused on analyzing and summarizing financial data rather than validating it. Applying condition rules relates to setting up parameters for specific workflows and calculations but does not inherently create or edit the messaging system. Reviewing ledger accounts pertains to examining recorded financial transactions but does not involve establishing the criteria that trigger error or warning messages.
