• What is the cause and solution for SAP error message DDLS128 - SQL view name & and DDL view name & cannot be identical ?

  The SAP error message DDLS128 indicates that there is a conflict between the SQL view name and the DDL (Data Definition Language) view name in your SAP system. Specifically, this error occurs when you attempt to create or modify a SQL view and the name of the SQL view is the same as the name of the DDL view.
  Cause:
  The primary cause of this error is that SAP enforces a naming convention that prevents SQL views and DDL views from having identical names. This is to avoid confusion and ensure that the system can differentiate between the two types of views.
  Solution:
  To resolve this error, you need to ensure that the SQL view and the DDL view have different names. Here are the steps you can take:
  
  
  Rename the SQL View or DDL View:
  
  If you are creating a new SQL view, choose a different name that does not conflict with any existing DDL view.
  If you are modifying an existing SQL view, consider renaming it to something unique.
  
  
  
  Check Existing Views:
  
  Use transaction codes like SE11 (Data Dictionary) or SE80 (Object Navigator) to check for existing views and their names.
  Ensure that the name you want to use for your SQL view is not already in use by a DDL view.
  
  
  
  Adjust Naming Conventions:
  
  If you are working in a team or a larger project, establish a naming convention that helps avoid such conflicts in the future.
  
  
  
  Recreate the View:
  
  If you have already created the view and are facing this error while trying to activate or modify it, you may need to delete the conflicting view and recreate it with a new name.
  
  
  
  Related Information:
