  The SAP error message CM_EHFND_FW_CALC_ENG079 with the description "Incorrect argument of power expression" typically occurs in the context of calculations or expressions in SAP systems, particularly when using the SAP HANA database or in the context of SAP's calculation views.
  Cause:
  This error usually arises due to one of the following reasons:
  
  Invalid Input Values: The power function is being called with invalid arguments. For example, if the base or exponent is negative or not a valid number, it can lead to this error.
  Data Type Mismatch: The arguments provided to the power function may not be of the expected data type (e.g., trying to use a string instead of a numeric type).
  Null Values: If any of the arguments are null, it can also trigger this error, as the power function cannot process null values.
  Mathematical Constraints: Certain mathematical constraints may not be satisfied, such as raising a negative number to a fractional power.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  Check Input Values: Ensure that the values being passed to the power function are valid. For example, if you are using a negative base with a fractional exponent, consider revising the logic.
  Data Type Validation: Verify that the data types of the arguments are correct. Convert them to the appropriate numeric types if necessary.
  Handle Null Values: Implement checks to handle null values before passing them to the power function. You can use conditional statements to provide default values or skip calculations when nulls are encountered.
  Review Calculation Logic: If the calculation logic is complex, review it to ensure that all mathematical operations are valid and that the inputs to the power function are as expected.
  Debugging: Use debugging tools or logs to trace the values being passed to the power function to identify where the invalid argument is coming from.
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for the specific version of the software you are using, as it may provide additional context or examples related to the power function and its usage.
