• What is the cause and solution for SAP error message EZ455 - Include &1 is used as user exit include and user top include ?

  The SAP error message EZ455 indicates that there is a conflict in the use of include files in your ABAP program. Specifically, it states that the include &1 is being used both as a user exit include and as a user top include. This can lead to issues in the program's execution because the system does not know which context to use for the include.
  Cause:
  
  Multiple Usage: The include file is being referenced in multiple contexts (as a user exit and as a top include), which is not allowed.
  Configuration Issues: There may be a misconfiguration in the program or the includes that are being used.
  Development Errors: The developer may have mistakenly included the same include file in different ways.
  
  Solution:
  
  Check Include Usage: Review the ABAP program to see where the include &1 is being used. Ensure that it is only included in one context (either as a user exit or as a top include).
  Modify the Program: If the include is necessary in both contexts, consider refactoring the code to separate the logic into different includes or modules that can be included appropriately without conflict.
  Consult Documentation: Refer to SAP documentation or guidelines regarding the use of user exits and includes to ensure compliance with best practices.
  Testing: After making changes, thoroughly test the program to ensure that it functions correctly without the error.
  
  Related Information:
  
  User Exits: User exits are predefined points in the SAP standard code where you can add your own custom code. They are typically used to enhance the functionality of standard SAP applications.
  Includes: Includes are used in ABAP to modularize code. They allow you to include common code in multiple programs without duplication.
  ABAP Development Guidelines: Familiarize yourself with ABAP development best practices to avoid such conflicts in the future.
  
  If the issue persists after following these steps, consider reaching out to your SAP support team or consulting with an experienced ABAP developer for further assistance.
