While the Oracle FDI documentation does outline the high-level logic behind metric calculations for ERP, HCM, SCM and all applicable functional pillars, I was not able to locate the same for Key Metrics.
Client teams often expect this to be available (when we had key user trainings sessions), so they can clearly understand how each metric is derived, validate the results against their source data, and ensure alignment with their internal reporting standards.
Including the outline logic for all major KPIs would significantly improve clarity, reduce back-and-forth during implementations, and help business users build confidence in the delivered analytics.
