• What is the cause and solution for SAP error message FDT_CORE460 - Invalid parameters: Expression type is set, but object type <> expression ?

  The SAP error message FDT_CORE460 indicates that there is a mismatch between the expected object type and the actual object type being used in an expression. This typically occurs in the context of SAP's Field Data Tool (FDT) or similar environments where expressions are defined for data processing.
  Cause:
  The error arises when:
  
  An expression is defined with a specific type, but the object being referenced does not match that type.
  For example, if an expression is expected to be of type "expression" but is being evaluated with an object of a different type (like a field or a constant), this error will be triggered.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Expression Definition:
  
  Review the expression that is causing the error. Ensure that the types of all components used in the expression are compatible with the expected type.
  
  
  
  Verify Object Types:
  
  Ensure that the objects (fields, constants, etc.) being used in the expression are of the correct type. If the expression is meant to work with a specific type, make sure that the objects being referenced conform to that type.
  
  
  
  Modify the Expression:
  
  If necessary, modify the expression to ensure that it only uses compatible types. This may involve changing the data type of certain fields or constants or adjusting the logic of the expression.
  
  
  
  Test the Changes:
  
  After making adjustments, test the expression again to see if the error persists. 
  
  
  
  Consult Documentation:
  
  If you are unsure about the types or how to define them correctly, refer to the SAP documentation or help resources related to the Field Data Tool or the specific module you are working with.
  
  
  
  Seek Help from SAP Support:
  
  If the issue continues and you cannot identify the cause, consider reaching out to SAP support or consulting with a colleague who has experience with the FDT.
