SAP Error Message - Details

• Message type: E = Error

• Message class: FDT_EXPRESSIONS - Formula & Derivation Tool: Expressions

• Message number: 339

• Message text: Condition must be based either on an expression or a range, not both (&1)

What causes this issue?

You have modified the condition for a an expression (changed element:
&V1&). A condition can be based either on a value range that has been
entered directly or on an expression. However, the modification you have
made would lead to a mixed condition based on both a range and an
expression at the same time. This is not allowed.
This situation can normally only occur if an application attempts to
programmatically modify a condition without taking care of the
restrictions as defined in the BRFplus API.

System Response

The changed object cannot be saved.

How to fix this error?

Check the application code used to change the object. Make sure that in
the application flow control, the type of an already defined condition
is determined first and then changed accordingly.

• What is the cause and solution for SAP error message FDT_EXPRESSIONS339 - Condition must be based either on an expression or a range, not both (&1) ?

  The SAP error message FDT_EXPRESSIONS339 indicates that there is an issue with the condition defined in a decision table or expression in the SAP system. Specifically, the error states that the condition must be based either on an expression or a range, but not both at the same time. This typically occurs in the context of using the Flexible Decision Table (FDT) framework in SAP.
  Cause:
  The error arises when a condition is incorrectly defined in a way that combines both an expression and a range. For example, if you are trying to set a condition that checks for a specific value (expression) and also checks if that value falls within a certain range simultaneously, the system does not allow this combination.
  Solution:
  To resolve this error, you need to review the condition that is causing the issue and modify it so that it adheres to the requirement of using either an expression or a range, but not both. Here are the steps you can take:
  
  
  Identify the Condition: Locate the specific condition in the decision table or expression that is causing the error.
  
  
  Modify the Condition:
  
  If you want to check for a specific value, ensure that you only use an expression (e.g., value = X).
  If you want to check for a range, use a range condition (e.g., value BETWEEN Y AND Z).
  
  
  
  Test the Changes: After making the necessary adjustments, test the decision table or expression to ensure that it works as expected without triggering the error.
  
  
  Documentation: If applicable, document the changes made for future reference and to help others understand the logic behind the conditions.
  
  
  Related Information:
  
  FDT Framework: The Flexible Decision Table framework in SAP allows users to define complex business rules and conditions in a structured manner. Understanding how to properly define conditions is crucial for effective use of this framework.
  SAP Notes and Documentation: Check SAP Notes or the official SAP Help documentation for any additional guidance or updates related to the FDT framework and error handling.
  Debugging: If you continue to face issues, consider using debugging tools within SAP to trace the execution and identify where the condition is being evaluated incorrectly.
  
  By following these steps, you should be able to resolve the FDT_EXPRESSIONS339 error and ensure that your conditions are defined correctly.
