• What is the cause and solution for SAP error message TRM_REGR_TOOL1001 - All y-values are zero ?

  The SAP error message TRM_REGR_TOOL1001, which states "All y-values are zero," typically occurs in the context of regression analysis within the SAP system, particularly when using the SAP Business Warehouse (BW) or SAP Analytics Cloud (SAC) for predictive analytics.
  Cause:
  This error indicates that the dependent variable (y-values) in your regression analysis contains only zero values. This situation can arise due to several reasons:
  
  Data Quality Issues: The dataset being analyzed may have been improperly prepared, leading to a situation where the dependent variable has no variation (i.e., all values are zero).
  Filtering or Selection Criteria: If filters or selection criteria are applied to the dataset, they may inadvertently exclude all non-zero values, resulting in a dataset where the dependent variable is entirely zero.
  Incorrect Data Mapping: There may be an issue with how the data is mapped or imported into the regression tool, leading to incorrect values being assigned to the dependent variable.
  
  Solution:
  To resolve the TRM_REGR_TOOL1001 error, consider the following steps:
  
  
  Check Data Source: Review the data source to ensure that the dependent variable (y-values) contains valid, non-zero data. You can do this by querying the dataset directly in the database or using a data preview tool.
  
  
  Data Preparation: If the dataset is found to have all zero values, you may need to revisit the data preparation steps. Ensure that the data is correctly aggregated, transformed, and that any necessary calculations are performed before running the regression analysis.
  
  
  Review Filters: Check any filters or selection criteria applied to the dataset. Ensure that they are not excluding all non-zero values. Adjust the filters as necessary to include relevant data.
  
  
  Data Mapping: Verify that the data mapping in the regression tool is correct. Ensure that the dependent variable is correctly identified and that the data is being pulled from the correct fields.
  
  
  Test with Sample Data: If possible, test the regression analysis with a smaller sample dataset that you know contains non-zero values to confirm that the regression tool is functioning correctly.
  
  
  Consult Documentation: Refer to SAP documentation or support resources for additional guidance on regression analysis and troubleshooting common errors.
  
  
  Related Information:
  
  Regression Analysis: Understand the basics of regression analysis, including the role of dependent and independent variables.
  Data Quality: Familiarize yourself with best practices for data quality and preparation in SAP BW or SAC.
  SAP Support: If the issue persists after troubleshooting, consider reaching out to SAP support for further assistance, providing them with details about your dataset and the steps you've taken to resolve the issue.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to successfully run your regression analysis.
