• What is the cause and solution for SAP error message RSAN_RT324 - Coefficient of determination r^2 = &1 ?

  The SAP error message RSAN_RT324, which indicates "Coefficient of determination r^2 = &1," typically arises in the context of SAP BW (Business Warehouse) or SAP HANA when dealing with statistical analyses or regression models. The coefficient of determination, denoted as r², is a statistical measure that represents the proportion of variance for a dependent variable that's explained by an independent variable or variables in a regression model.
  
  Cause:
  The error message RSAN_RT324 usually occurs when the calculated r² value is either not valid or falls outside the expected range (0 to 1). This can happen due to several reasons, including:
  
  Insufficient Data: The dataset used for the regression analysis may not have enough data points to produce a reliable r² value.
  Poor Model Fit: The model may not fit the data well, leading to an r² value that is not meaningful.
  Data Quality Issues: There may be issues with the data quality, such as missing
