  The SAP error message FDT_HANA196 typically occurs in the context of SAP HANA when working with calculation views or data flows. This error indicates that a result data object (like a column or a measure) needs to be calculated using an expression, but it has not been defined properly.
  Cause:
  
  Missing Expression: The result data object is expected to have a calculation or expression defined, but it is either missing or incorrectly configured.
  Incorrect Data Type: The data type of the result object may not match the expected type for the operation being performed.
  Improper Configuration: The configuration of the calculation view or data flow may not be set up correctly, leading to the inability to compute the result.
  
  Solution:
  
  
  Define the Expression: Ensure that the result data object has a valid expression defined. This can be done by:
  
  Opening the calculation view or data flow in the SAP HANA Studio or Web IDE.
  Navigating to the result data object and checking its properties.
  Adding or correcting the expression as needed.
  
  
  
  Check Data Types: Verify that the data types of the input fields and the result object are compatible. If there is a mismatch, adjust the data types accordingly.
  
  
  Review Configuration: Go through the entire configuration of the calculation view or data flow to ensure that all necessary components are properly set up. This includes checking joins, unions, and any other transformations that may affect the result.
  
  
  Test the Expression: After making changes, test the expression to ensure it calculates correctly. You can do this by executing the calculation view or data flow and checking the output.
