Smart SAP Assistant

• What is the cause and solution for SAP error message FCOM_PLANNING_CORE120 - Start solving set of &1 linear equations by using matrix inversion (L) ?

  The SAP error message FCOM_PLANNING_CORE120 typically relates to issues encountered during the planning process in SAP, particularly when dealing with linear equations and matrix operations. This error indicates that the system is attempting to solve a set of linear equations using matrix inversion, but it has encountered a problem.
  Causes:
  
  
  Singular Matrix: The matrix that the system is trying to invert may be singular (non-invertible), which means that it does not have a unique solution. This can happen if the equations are dependent or if there are not enough independent equations to solve for the variables.
  
  
  Data Issues: There may be missing or incorrect data in the planning tables or master data that is causing the matrix to be improperly defined.
  
  
  Configuration Issues: Incorrect configuration in the planning settings or parameters can lead to problems in how the equations are set up.
  
  
  Resource Constraints: Insufficient system resources (like memory) can also lead to issues when performing complex calculations.
  
  
  Solutions:
  
  
  Check Data Integrity: Review the input data for completeness and correctness. Ensure that all necessary master data and transactional data are available and correctly configured.
  
  
  Review Planning Parameters: Check the planning parameters and settings in the configuration. Ensure that they are set up correctly to avoid issues with the equations being generated.
  
  
  Matrix Condition: Analyze the matrix being used for inversion. If it is singular, you may need to adjust the equations or the data to ensure that they are independent and can be solved.
  
  
  Debugging: If you have access to debugging tools, you can trace the execution to see where the error occurs and gather more information about the state of the matrix and the equations.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to the specific planning module you are using. There may be known issues or patches available.
  
  
  Contact SAP Support: If the issue persists and you cannot identify the cause, consider reaching out to SAP support for assistance. They may have additional insights or solutions based on the specific context of your implementation.
