• What is the cause and solution for SAP error message AD091 - First 7 characters of name & are identical to the view table name ?

  The SAP error message AD091 indicates that there is a naming conflict in the system. Specifically, it means that the first seven characters of the name you are trying to use for a new object (like a table, view, or other database object) are identical to the name of an existing view or table in the database. This is a restriction in SAP to avoid confusion and ensure that object names are unique enough to prevent ambiguity.
  Cause:
  
  The error occurs when you attempt to create or modify an object (like a table or view) and the name you are using shares the first seven characters with an existing object in the database. This is a safeguard to prevent naming collisions and ensure clarity in object identification.
  
  Solution:
  
  
  Rename the Object: The most straightforward solution is to choose a different name for your object that does not conflict with existing names. Ensure that the new name does not share the first seven characters with any existing view or table names.
  
  
  Check Existing Objects: Before creating a new object, check the existing tables and views in the database to ensure that your desired name does not conflict. You can do this by using transaction codes like SE11 (Data Dictionary) or SE80 (Object Navigator) to search for existing objects.
  
  
  Use a Naming Convention: Implement a naming convention that helps avoid such conflicts in the future. For example, you could use prefixes or suffixes that are unique to your development area or project.
  
  
  Consult Documentation: If you are unsure about the naming conventions or the existing objects, consult the SAP documentation or your organization's development guidelines.
  
  
  Related Information:
  
  SAP Naming Conventions: Familiarize yourself with SAP's naming conventions for database objects. This can help you avoid conflicts and ensure that your objects are easily identifiable.
  Transaction Codes: Use transaction codes like SE11 (Data Dictionary) to view existing tables and views, and SE80 (Object Navigator) for a broader view of all objects in the system.
  Development Guidelines: If you are working in a team or organization, check if there are specific development guidelines or standards that you should follow regarding object naming.
  
  By following these steps, you should be able to resolve the AD091 error and successfully create or modify your SAP objects without naming conflicts.
