• What is the cause and solution for SAP error message FDT_EXPRESSIONS028 - No operands set ?

  The SAP error message FDT_EXPRESSIONS028: No operands set typically occurs in the context of using the SAP Fiori Design Studio or SAP Business Application Studio when working with expressions in the context of data binding or calculations. This error indicates that an expression is expected to have operands (variables or values) defined, but none have been set.
  Cause:
  
  Missing Operands: The expression you are trying to evaluate does not have any operands defined. This could happen if you are trying to create a calculation or a condition without specifying the necessary variables or values.
  Incorrect Expression Syntax: The syntax of the expression might be incorrect, leading to the system not recognizing any operands.
  Data Binding Issues: If the expression is supposed to bind to data from a model, there might be issues with the data model or the binding path.
  
  Solution:
  
  
  Check Expression Syntax: Review the expression you are using to ensure that it is correctly formatted and includes the necessary operands. Make sure that all variables or values you intend to use are properly referenced.
  
  
  Define Operands: If you are using a calculation or condition, ensure that you have defined all required operands. For example, if you are trying to perform a mathematical operation, make sure that all variables involved in the operation are set.
  
  
  Review Data Binding: If the expression relies on data from a model, check that the data model is correctly defined and that the binding paths are accurate. Ensure that the data is available at runtime.
  
  
  Debugging: Use debugging tools available in the SAP environment to trace the execution and see where the expression is failing. This can help identify if the issue is with the data or the expression itself.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific version you are using to understand the expected syntax and requirements for expressions.
