• What is the cause and solution for SAP error message FDT_SERVICE012 - Element types &1 and &2 must not be compared with operator &3 ?

  The SAP error message FDT_SERVICE012 indicates that there is an issue with comparing two different element types using a specific operator in a formula or expression. This error typically arises in the context of SAP's Flexible Data Import (FDI) or similar data processing scenarios where data types must be compatible for comparison operations.
  Cause:
  The error occurs when:
  
  You are trying to compare two elements (e.g., fields, variables) that are of incompatible types. For example, comparing a string with a number, or a date with a string.
  The operator used for comparison (e.g., =, <>, <, >, etc.) is not suitable for the types of the elements being compared.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Data Types: Verify the data types of the elements you are trying to compare. Ensure that they are compatible. For instance, if you are comparing a numeric field with a string, you may need to convert one of the fields to match the other type.
  
  
  Type Conversion: If necessary, use appropriate type conversion functions to convert one of the elements to the type of the other. For example:
  
  Use TO_NUMBER() to convert a string to a number.
  Use TO_STRING() to convert a number to a string.
  
  
  
  Review the Logic: Ensure that the logic of your comparison makes sense. Sometimes, the comparison itself may not be valid based on the business logic you are implementing.
  
  
  Check the Operator: Make sure that the operator you are using is appropriate for the types of the elements. For example, using = for equality checks between compatible types.
  
  
  Debugging: If you are unsure about the types being compared, you can add debugging statements or logs to output the types of the elements before the comparison.
  
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for Flexible Data Import or the specific module you are working with for more details on data types and comparison operations.
  Data Type Compatibility: Familiarize yourself with the data types used in your SAP environment, as different modules may have specific requirements for data types.
  Community Forums: Check SAP community forums or support channels for similar issues and solutions shared by other users.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
