• What is the cause and solution for SAP error message SALV_EXCEPTION013 - Object &1 &2 already exists (class &3 method &4) ?

  The SAP error message SALV_EXCEPTION013 indicates that an object you are trying to create or manipulate already exists in the context of the SAP ALV (ABAP List Viewer) framework. This error typically occurs when you attempt to create a new instance of an ALV object (like a grid or a list) that has already been instantiated.
  Cause:
  The error can occur due to several reasons:
  
  Duplicate Object Creation: You are trying to create an ALV object (like a grid) that has already been created in the same context or session.
  Improper Object Management: The code does not properly manage the lifecycle of ALV objects, leading to attempts to create the same object multiple times.
  Incorrect Logic in Code: There may be logical errors in the code that lead to the creation of the same object under certain conditions.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Object Existence: Before creating a new ALV object, check if it already exists. You can use a conditional statement to verify the existence of the object.
  IF NOT assigned( lo_alv ).
      CREATE OBJECT lo_alv.
  ENDIF.
  
  
  Proper Object Management: Ensure that you are managing the lifecycle of your ALV objects correctly. If you are done with an ALV object, make sure to free it or set it to NULL before trying to create it again.
  
  
  Debugging: Use debugging tools to trace the execution of your code and identify where the duplicate creation is happening. Look for loops or conditions that might lead to multiple instantiations.
  
  
  Refactor Code: If the logic is complex, consider refactoring your code to simplify the creation and management of ALV objects. This can help prevent accidental duplicate creations.
  
  
  Review Documentation: Check the SAP documentation for the specific ALV classes and methods you are using to ensure you are following best practices.
  
  
  Related Information:
  
  ALV Framework: The ALV framework in SAP is used for displaying lists and reports in a user-friendly manner. Understanding how it works can help in managing objects effectively.
  ABAP Object-Oriented Programming: Familiarity with ABAP OOP concepts is essential for managing object lifecycles and avoiding such errors.
  SAP Notes: Check SAP Notes for any known issues or patches related to the ALV framework that might address this error.
  
  By following these steps, you should be able to resolve the SALV_EXCEPTION013 error and prevent it from occurring in the future.
