  The SAP error message CM_EHFND_FW_CALC_ENG071 indicates that there is an issue with a square root calculation where the argument value is negative. The message specifically states that the square root argument value "&1" is out of domain (>=0), meaning that the calculation is attempting to take the square root of a number that is less than zero, which is mathematically undefined in the realm of real numbers.
  Cause:
  
  Negative Input Value: The most common cause of this error is that the input value being passed to the square root function is negative. This could be due to incorrect data, calculations, or logic in the program.
  Data Integrity Issues: There may be issues with the data being processed, such as missing or incorrect values that lead to negative results.
  Business Logic Errors: The logic used to derive the value for the square root calculation may not be correctly implemented, leading to unexpected negative values.
  
  Solution:
  
  Check Input Values: Review the input values being used in the calculation. Ensure that they are valid and non-negative. You can add validation checks before performing the square root operation.
  Debugging: Use debugging tools to trace the execution of the program and identify where the negative value is being generated. This will help you understand the flow of data and logic.
  Data Validation: Implement data validation rules to ensure that only valid, non-negative values are processed. This can include checks at the point of data entry or before calculations.
  Error Handling: Add error handling to manage cases where the input value is negative. This could involve logging the error, notifying the user, or providing a default value.
  Review Business Logic: If the calculation is based on business logic, review the logic to ensure it is correctly implemented and that it accounts for all possible scenarios that could lead to a negative value.
