• What is the cause and solution for SAP error message AC395 - Do not change objects in the SAP name range ?

  The SAP error message AC395, which states "Do not change objects in the SAP name range," typically occurs when a user attempts to modify or create objects (such as tables, fields, or other database objects) that fall within the SAP namespace. The SAP namespace is reserved for SAP's own development and should not be altered by customers or third-party developers to ensure system integrity and stability.
  Cause:
  
  Namespace Violation: The user is trying to create or modify an object that is within the SAP reserved namespace (usually starting with "SAP" or "S" followed by a number).
  Development Environment: This error often occurs in development environments where users may not have the necessary authorizations or are not following the naming conventions.
  Transport Requests: If you are trying to transport objects that are in the SAP namespace, this error can also occur.
  
  Solution:
  
  Use Customer Namespace: Always create or modify objects in your own customer namespace (usually starting with "Z" or "Y"). This ensures that you are not conflicting with SAP's reserved objects.
  Check Object Names: Review the names of the objects you are trying to create or modify. Ensure they do not start with "SAP" or fall within the SAP reserved range.
  Authorization Check: Ensure that you have the necessary authorizations to create or modify objects in the system. If you are unsure, consult with your SAP Basis or security team.
  Development Guidelines: Follow SAP's development guidelines and best practices to avoid namespace conflicts. This includes using proper naming conventions and adhering to the development standards set by your organization.
