• What is the cause and solution for SAP error message RSAN_RT301 - No solution for the linear regression ?

  The SAP error message RSAN_RT301, which states "No solution for the linear regression," typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when attempting to perform linear regression analysis on a dataset. This error indicates that the algorithm was unable to compute a valid solution for the regression model based on the provided data.
  Causes of RSAN_RT301
  
  
  Insufficient Data: The dataset may not contain enough data points to perform a linear regression analysis. Linear regression requires a minimum number of observations to establish a relationship.
  
  
  Collinearity: If the independent variables in the regression model are highly correlated with each other (multicollinearity), it can lead to instability in the regression coefficients, resulting in no valid solution.
  
  
  Data Quality Issues: Missing values, outliers, or incorrect data types can affect the regression analysis. If the data is not clean or properly formatted, the algorithm may fail to compute a solution.
  
  
  Inappropriate Model Specification: The
