• What is the cause and solution for SAP error message FDT_WD_EXPRESSION060 - Result Data Object set to number ?

  The SAP error message FDT_WD_EXPRESSION060 typically indicates an issue with the data type of a result data object in a Web Dynpro application. Specifically, it suggests that the result data object is expected to be of a certain type (like a string or a structure), but it has been set to a number instead. This can occur in scenarios where expressions or calculations are being evaluated, and the expected data type does not match the actual data type being provided.
  Cause:
  
  Data Type Mismatch: The most common cause of this error is that the expression or calculation is returning a numeric value, but the target data object is defined to accept a different data type (e.g., string or structure).
  Incorrect Configuration: The configuration of the Web Dynpro component may not align with the expected data types, leading to this error.
  Expression Logic: The logic used in the expression may inadvertently produce a numeric result when a different type is expected.
  
  Solution:
  
  Check Data Types: Review the data types of the result data object and the expression. Ensure that they are compatible. If the result is a number, the target data object should also be defined to accept a number.
  Modify Expression: If the expression is intended to return a different type, modify it to ensure it returns the correct data type. For example, if a string is expected, convert the number to a string using appropriate functions.
  Adjust Component Configuration: If the data object is incorrectly configured, adjust the Web Dynpro component's configuration to ensure that the data types align correctly.
  Debugging: Use debugging tools to trace the execution of the Web Dynpro application and identify where the data type mismatch occurs. This can help pinpoint the exact location of the issue.
