• What is the cause and solution for SAP error message DDLST018 - Entity & cannot be renamed to &; DDL source & is already delivered. ?

  The SAP error message DDLST018 indicates that there is an issue with renaming an entity (such as a table, view, or other database object) because the DDL (Data Definition Language) source is already delivered. This typically occurs in the context of ABAP Dictionary objects or when working with transport requests in SAP.
  Cause:
  
  Entity Already Delivered: The entity you are trying to rename has already been delivered to a target system (e.g., production). SAP does not allow renaming of objects that are part of a transport request that has already been released and imported into another system.
  Transport Request Issues: The transport request containing the original entity may have been released, and the system is preventing changes to ensure data integrity and consistency across systems.
  Dependencies: There may be dependencies or references to the entity that prevent it from being renamed.
  
  Solution:
  
  Check Transport Status: Verify the status of the transport request that contains the entity. If it has been released and imported, you will need to create a new transport request for any changes.
  Create a New Entity: Instead of renaming the existing entity, consider creating a new entity with the desired name and migrating any necessary data or references to the new entity.
  Modify the Original Entity: If renaming is essential, you may need to revert the transport request or make changes in the development environment before re-releasing it. This may involve un-releasing the transport request, which is not always possible.
  Consult Documentation: Review SAP documentation or notes related to DDL operations and transport management for specific guidelines and best practices.
  Contact SAP Support: If the issue persists or if you are unsure about the steps to take, consider reaching out to SAP support for assistance.
  
  Related Information:
