  The SAP error message /SAPAPO/ESPP_PR449 White noise detected typically occurs in the context of SAP Advanced Planning and Optimization (APO) when the system identifies that the forecast model is not able to generate meaningful predictions due to erratic or random fluctuations in the historical data.
