• What is the cause and solution for SAP error message FDT_EXPRESSIONS808 - Static method call isn't possible, method &1 has a raw parameter ?

  The SAP error message FDT_EXPRESSIONS808 indicates that there is an issue with a static method call in your ABAP code or in the context of using the Field Data Tool (FDT). The specific message states that the method you are trying to call has a raw parameter, which is not allowed for static method calls.
  Cause:
  The error occurs when you attempt to call a static method that has a parameter defined as a raw type (e.g., RAW, XSTRING, etc.). In ABAP, static methods cannot accept raw parameters because they are not compatible with the way static methods are designed to work. Static methods are typically used for utility functions that do not depend on instance-specific data.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Method Definition: Review the method definition of the method you are trying to call. If it has a raw parameter, consider changing the parameter type to a more compatible type, such as STRING or CHAR, if that fits your use case.
  
  
  Change Method Call: If you cannot change the method definition (for example, if it is part of a standard SAP class), you may need to create an instance of the class and call the method as an instance method instead of a static method.
  
  
  Refactor Code: If the method is designed to work with raw data, consider refactoring your code to handle the data in a way that does not require a static method call. This might involve creating a wrapper function or using a different approach to achieve the desired functionality.
  
  
  Consult Documentation: If you are using a third-party library or a specific SAP component, consult the documentation for that component to see if there are any guidelines or best practices regarding method calls and parameter types.
  
  
  Related Information:
  
  ABAP Method Types: Understand the difference between static and instance methods in ABAP. Static methods belong to the class itself, while instance methods belong to an instance of the class.
  Parameter Types: Familiarize yourself with the different parameter types in ABAP and their compatibility with static method calls.
  SAP Notes: Check for any relevant SAP Notes or Knowledge Base Articles (KBAs) that might address this specific error or provide additional context.
  
  By following these steps, you should be able to resolve the error and successfully call the method without encountering the FDT_EXPRESSIONS808 message.
