• What is the cause and solution for SAP error message FDT_SERVICE011 - Data object types &1 and &2 must not be compared with operator &3 ?

  The SAP error message FDT_SERVICE011 indicates that there is an issue with comparing two data object types that are not compatible with the specified operator. This typically occurs in the context of data transformation or data processing within SAP, particularly when using the SAP Data Services or similar tools.
  Cause:
  The error arises when you attempt to compare two data objects (e.g., fields, variables) of different types using an operator that is not valid for those types. For example, you might be trying to compare a string with a number, or a date with a string, using an operator like =, <>, <, >, etc. The system does not allow such comparisons because they do not make logical sense.
  Solution:
  To resolve this error, you should:
  
  
  Check Data Types: Review the data types of the objects you are trying to compare. Ensure that both objects are of compatible types. You can do this by checking the definitions of the data objects in the relevant data model or transformation logic.
  
  
  Type Conversion: If the data types are indeed different but you need to compare them, consider converting one of the data types to match the other. For example:
  
  If you are comparing a string to a number, convert the string to a number using appropriate conversion functions.
  If you are comparing a date to a string, convert the date to a string format that matches the expected format.
  
  
  
  Use Appropriate Operators: Ensure that you are using the correct operators for the data types you are working with. For example, if you are comparing numeric values, use numeric comparison operators.
  
  
  Review Logic: If the comparison is part of a larger logic or condition, review the overall logic to ensure that the comparisons make sense in the context of your application.
  
  
  Related Information:
  
  Data Type Documentation: Refer to SAP documentation for details on data types and their compatibility.
  Transformation Logic: If you are using a specific transformation tool (like SAP Data Services), consult the documentation for that tool to understand how to handle data type conversions and comparisons.
  Debugging: Use debugging tools available in SAP to step through the logic and identify where the incompatible comparison is occurring.
  
  By following these steps, you should be able to identify the root cause of the error and implement a solution to resolve it.
