• What is the cause and solution for SAP error message FDT_EXPRESSIONS085 - Result might not be compatible with result of target function &1 &2 &3 ?

  The SAP error message FDT_EXPRESSIONS085 indicates that there is a compatibility issue with the result type of an expression in a function. This typically occurs in the context of using the SAP Fiori Design Time (FDT) or when working with expressions in SAP applications, particularly in the context of data transformation or calculations.
  Cause:
  The error arises when the result type of an expression does not match the expected result type of the target function. This can happen due to several reasons:
  
  Data Type Mismatch: The expression is returning a data type that is not compatible with what the target function expects. For example, if the target function expects a numeric value but the expression returns a string.
  Incorrect Function Usage: The function being called may not be appropriate for the type of data being passed to it.
  Complex Expressions: If the expression is complex and involves multiple operations, it may lead to unexpected data types being returned.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Data Types: Review the data types of the variables and expressions involved. Ensure that the output of your expression matches the expected input type of the target function.
  
  
  Use Type Conversion: If there is a mismatch, consider using type conversion functions to convert the data type of the expression to the expected type. For example, you can use functions like TO_NUMBER, TO_STRING, etc., depending on the required conversion.
  
  
  Review Function Documentation: Check the documentation for the target function to understand what data types it accepts. This will help you ensure that you are using the function correctly.
  
  
  Simplify Expressions: If the expression is complex, try breaking it down into simpler parts to isolate the issue. This can help you identify where the type mismatch is occurring.
  
  
  Debugging: Use debugging tools available in SAP to step through the code and inspect the values and types being passed around. This can provide insights into where the incompatibility arises.
  
  
  Consult SAP Notes: Sometimes, specific issues may be documented in SAP Notes. Check the SAP Support Portal for any relevant notes that might address this error.
  
  
  Related Information:
  
  SAP Fiori Design Time (FDT): Familiarize yourself with the FDT environment and how expressions are evaluated within it.
  Data Types in ABAP: Understanding the various data types in ABAP (e.g., CHAR, NUMC, DEC, etc.) can help in ensuring compatibility.
  Function Module Documentation: Review the documentation for any function modules or methods you are using to understand their expected input and output types.
  
  By following these steps, you should be able to identify and resolve the compatibility issue causing the FDT_EXPRESSIONS085 error.
