• What is the cause and solution for SAP error message FCOM_PLANNING_CORE118 - Start solving set of &1 linear eqns by using Gauss-Seidel method (ABAP) ?

  The SAP error message FCOM_PLANNING_CORE118 indicates an issue related to the linear equations being solved using the Gauss-Seidel method in the context of financial or planning applications within SAP. This error typically arises during the execution of planning functions or calculations that involve solving a set of linear equations.
  Cause:
  
  Data Issues: The input data for the linear equations may be incorrect or incomplete. This could include missing values, incorrect data types, or invalid configurations.
  Matrix Singularity: The matrix formed by the coefficients of the linear equations may be singular or nearly singular, meaning it does not have a unique solution.
  Insufficient Iterations: The Gauss-Seidel method may not have converged to a solution within the allowed number of iterations.
  Configuration Errors: There may be issues with the configuration of the planning function or the parameters set for the calculation.
  
  Solution:
  
  Check Input Data: Review the input data for the planning function to ensure that all required values are present and correctly formatted. Look for any missing or invalid entries.
  Matrix Validation: Analyze the coefficients of the linear equations to ensure that the matrix is not singular. You may need to adjust the equations or the data to ensure a unique solution exists.
  Increase Iterations: If the method is not converging, consider increasing the maximum number of iterations allowed for the Gauss-Seidel method in the planning function settings.
  Review Configuration: Check the configuration of the planning function and ensure that all parameters are set correctly. This includes reviewing any custom logic or enhancements that may affect the calculation.
  Debugging: If you have access to the ABAP code, you can debug the function to identify where the error occurs and gather more context about the input data and the state of the calculations.
