  The SAP error message FCOM_PLANNING_CORE106: Matrix cannot be inverted. Please contact SAP typically occurs in the context of financial planning or forecasting processes within SAP systems, particularly when using the SAP Analytics Cloud (SAC) or SAP Business Planning and Consolidation (BPC). This error indicates that there is an issue with a matrix (or a set of data) that is required for calculations, and it cannot be inverted due to certain mathematical properties.
  Causes:
  
  
  Singular Matrix: The most common cause of this error is that the matrix involved in the calculation is singular, meaning it does not have an inverse. This can happen if:
  
  There are linearly dependent rows or columns in the matrix.
  The matrix contains rows or columns of zeros.
  The matrix is not square (i.e., the number of rows does not equal the number of columns).
  
  
  
  Data Issues: There may be issues with the data being used in the planning model, such as:
  
  Missing or incorrect data entries.
  Data types that are not compatible with the calculations.
  
  
  
  Configuration Issues: Incorrect configuration of the planning model or parameters can lead to this error.
  
  
  Software Bugs: Occasionally, this error may arise due to bugs in the SAP software itself.
  
  
  Solutions:
  
  
  Check Data Integrity:
  
  Review the data being used in the planning model to ensure there are no missing values or incorrect entries.
  Ensure that the data is complete and that there are no rows or columns that are entirely zero.
  
  
  
  Matrix Properties:
  
  Verify that the matrix is square and that it does not have linearly dependent rows or columns.
  If applicable, try to simplify the model or reduce the number of variables to avoid singular matrices.
  
  
  
  Model Configuration:
  
  Review the configuration of the planning model to ensure that it is set up correctly.
  Check for any recent changes in the model that might have introduced the issue.
  
  
  
  Debugging:
  
  If you have access to debugging tools, you can trace the calculations leading to the error to identify the specific matrix causing the issue.
