• What is the cause and solution for SAP error message RSAN_RT302 - No unique solution for the linear regression ?

  The SAP error message RSAN_RT302, which states "No unique solution for the linear regression," typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when performing linear regression analysis. This error indicates that the algorithm used for linear regression could not find a unique solution based on the input data provided.
  Causes:
  
  Multicollinearity: This occurs when two or more independent variables in the regression model are highly correlated, leading to redundancy and making it difficult to determine the individual effect of each variable.
  Insufficient Data: If there are not enough data points relative to the number of variables, the regression model may not be able to compute a unique solution.
  Perfect Multicollinearity: This is a more severe case of multicollinearity where one independent variable is a perfect linear combination of others.
  Data Quality Issues: Missing values, outliers, or incorrect data types can also lead to problems in regression analysis.
  Inappropriate Model Specification: If
