• What is the cause and solution for SAP error message /BA1/F4_MATH_TOOLS004 - QR decomposition; cannot decompose due to unsuitable input parameters ?

  The SAP error message /BA1/F4_MATH_TOOLS004 QR decomposition; cannot decompose due to unsuitable input parameters typically occurs in the context of mathematical computations, particularly when attempting to perform QR decomposition on a matrix. QR decomposition is a method used in numerical linear algebra to factor a matrix into an orthogonal matrix (Q) and an upper triangular matrix (R). 
  
  Cause:
  The error indicates that the input parameters provided to the QR decomposition function are unsuitable. This can happen due to several reasons:
  
  
  Matrix Size: The matrix may not be of the appropriate size. For QR decomposition, the matrix should ideally be a rectangular matrix (m x n) where m = n. If the matrix is singular or has more rows than columns, it may lead to this error.
  
  
  Singular Matrix: If the matrix is singular (i.e., it does not have full rank), the QR decomposition cannot be performed. This often occurs when there are linearly
