• What is the cause and solution for SAP error message FDT_EXPRESSIONS537 - Incorrect usage of operator &1 with type &2 ?

  The SAP error message FDT_EXPRESSIONS537 indicates that there is an incorrect usage of an operator in a formula or expression within the context of SAP's Field Data Tool (FDT) or similar environments. The message specifies that the operator (&1) is being used with a data type (&2) that is not compatible with it.
  Cause:
  This error typically arises due to one of the following reasons:
  
  Type Mismatch: The operator being used is not suitable for the data type of the operands. For example, trying to use a mathematical operator on a string type.
  Incorrect Operator: The operator itself may not be valid for the context in which it is being used.
  Logical Errors: There may be logical errors in the expression that lead to the use of an operator inappropriately.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Expression: Review the expression or formula where the error occurs. Ensure that the operator is appropriate for the data types involved.
  
  
  Data Type Verification: Verify the data types of the operands. You can do this by checking the definitions of the fields or variables being used in the expression.
  
  
  Correct the Operator: If the operator is indeed incorrect for the data type, replace it with a suitable operator. For example, if you are trying to concatenate strings, use the appropriate string concatenation operator instead of a mathematical operator.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific operators and their valid data types. This can help clarify which operators can be used with which data types.
  
  
  Testing: After making changes, test the expression to ensure that it now works without errors.
