• What is the cause and solution for SAP error message /BA1/F4_MATH_TOOLS002 - QR decomposition: matrix is singular ?

  The SAP error message /BA1/F4_MATH_TOOLS002 QR decomposition: matrix is singular typically indicates that a mathematical operation involving QR decomposition has failed because the matrix being processed is singular. A singular matrix is one that does not have an inverse, which can occur for several reasons, such as:
  Causes:
  
  Linearly Dependent Rows/Columns: The matrix may have rows or columns that are linearly dependent, meaning one row or column can be expressed as a linear combination of others.
  Insufficient Data: The data used to create the matrix may not be sufficient or may not vary enough, leading to a lack of rank.
  Zero Rows/Columns: The presence of rows or columns that are entirely zeros can also lead to singularity.
  Numerical Issues: In some cases, numerical precision issues can cause a matrix that should be non-singular to be treated as singular.
  
  Solutions:
  
  Check Data Quality: Review the data used to create the matrix. Ensure that there are no zero rows
