This feature introduces a structured logging framework to track the lifecycle of customer invoice documents, including sales orders and free text invoices (FTI). The logged data supports a detailed posting history in the Customer Invoice workspace, improving traceability and diagnostics. The tab pages in the Customer Invoicing workspace (e.g., Sales Order Posting History, FTI Posting History) remain unchanged before and after enabling this feature. Users can now view detailed error messages for sales orders that failed during the posting process. The Sales Order Posting History and FTI Posting History tabs continue to display data for the past 14 days by default, as per the current retention policy.
