• What is the cause and solution for SAP error message SEEF_BASE091 - PRE method already exists for & ?

  The SAP error message SEEF_BASE091, which states "PRE method already exists for &," typically occurs in the context of ABAP programming, particularly when dealing with class methods. This error indicates that there is an attempt to define a method (in this case, a "PRE" method) that has already been defined in the class or interface.
  Cause:
  
  
  Duplicate Method Definition: The most common cause of this error is that the method you are trying to define already exists in the class or interface. This can happen if:
  
  You are trying to create a method with the same name and signature as an existing method.
  You are copying code from another class or interface without checking for existing methods.
  
  
  
  Inheritance Issues: If the class is inheriting from a superclass or implementing an interface that already has a method with the same name, this can also lead to this error.
  
  
  Solution:
  
  
  Check Existing Methods: Review the class or interface where you are trying to define the method. Look for any existing methods with the same name and signature. You can do this by:
  
  Using the Class Builder (SE24) or Interface Builder (SE80) to inspect the methods of the class/interface.
  Searching for the method name in the ABAP editor.
  
  
  
  Rename the Method: If you find that the method already exists and you need to create a new one, consider renaming your method to avoid the conflict.
  
  
  Modify the Existing Method: If the existing method is not fulfilling your requirements, you may consider modifying it instead of creating a new one.
  
  
  Check Inheritance: If your class is inheriting from a superclass or implementing an interface, ensure that you are not unintentionally overriding a method. If you need to override, use the REDEFINITION keyword appropriately.
  
  
  Use Unique Method Names: As a best practice, always use unique and descriptive names for methods to avoid such conflicts in the future.
  
  
  Related Information:
  
  ABAP Class and Method Naming Conventions: Familiarize yourself with naming conventions in ABAP to avoid conflicts.
  Method Overriding: Understand how method overriding works in ABAP, especially in the context of inheritance.
  SAP Documentation: Refer to the official SAP documentation for more details on class and method definitions.
  
  By following these steps, you should be able to resolve the SEEF_BASE091 error and successfully define your methods in SAP ABAP.
