  The SAP error message FDT_HANA190 typically occurs in the context of SAP HANA when working with Field-Based Data Transformation (FDT) or similar data processing scenarios. The error message indicates that a source field is being used in a way that is not allowed, specifically in conjunction with an expression or parameter.
  Cause:
  The error arises when:
  
  A source field is being referenced in a transformation or calculation where it is not permitted.
  The source field is being used in a context that expects a different type of input, such as an expression or parameter.

  Modify the Expression:
  
  If you are using an expression or parameter, ensure that you are not directly referencing the source field in a way that is not allowed. You may need to adjust the expression to avoid using the source field directly.
  
  
  
  Check Data Types:
  
  Ensure that the data types of the source field and the expected input for the expression or parameter are compatible. If there is a mismatch, you may need to cast or convert the data types appropriately.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation for Field-Based Data Transformation or the specific context in which you are working. This can provide insights into the correct usage of fields, expressions, and parameters.
